How Much More Expensive Is Xi'an Shenghongchuang's Wireless Transmission Pressure Transmitter Compared with the Wired Version? Where Is the Extra Cost Mainly Spent?

The complete unit price of Xi'an Shenghongchuang wireless transmission pressure transmitters is usually 30% to 65% higher than that of wired models with the same specifications. The specific fluctuation depends on configurations such as the communication protocol type, battery life requirements, explosion-proof rating, and data upload frequency. The price difference is not a fixed proportion, but rather a modular cost accumulation driven by actual functional requirements.

This question matters because whether the extra cost is worthwhile does not depend on whether it is “expensive or not,” but on whether it “saves or not”——whether it can reduce wiring and installation costs, shorten later maintenance downtime, and avoid scenarios where cable laying is restricted. When making a judgment, the first thing to check is whether the site has conditions that make wired deployment difficult, such as frequent manual inspections, long-distance points without power supply, corrosion/high temperature/explosion-proof requirements.

For the Extra Money Spent on the Wireless Version, Which Hardware Components Does It Actually Go To?

Three types of hardware costs are mainly added: low-power RF communication modules (such as LoRa, NB-IoT or proprietary 2.4G protocols), industrial-grade long-life batteries (including charge-discharge management circuits), and reinforced housings and sealing structures (adapted for wireless signal penetration and EMC anti-interference). Among them, communication modules account for about 45% of the incremental cost, battery systems about 30%, and the rest goes to structural and certification adaptation investment.

These are not as simple as “adding a WiFi module,” but must meet rigid industrial-site indicators such as 7×24 continuous operation, wide-temperature operation from -20℃~70℃, protection above IP66, and at least 2 years of battery-free replacement, so the selection and testing cycle is longer.

Whether a high-cost wireless solution is needed mainly depends on whether the site has a stable power supply and cable routing paths available. If mature wired infrastructure already exists and there are no obstacles to modification, the wireless premium may not necessarily bring comprehensive efficiency improvements.

Besides Hardware, What Hidden Costs Are Included in the Quotation?

Wireless solutions often include soft delivery items such as protocol stack licensing fees, remote configuration platform access licenses, and factory preset network parameter commissioning services. These will not be listed separately, but they form part of the complete unit quotation.

In addition, some models need to pass wireless transmitting equipment model approval (SRRC) and intrinsic safety/flameproof certification. The certification cycle and testing fees are also amortized into the cost per unit. Since wired models do not require RF transmission, they usually do not involve such mandatory certifications.

Whether hidden costs actually arise depends on whether the user enables cloud platform management, whether explosion-proof qualifications are required, and whether a designated network operator is specified. If it is only used for local short-distance transparent transmission, simplified configurations may be negotiated to control the total price.

Under What Circumstances Might the Wireless Version Actually Be “Cheaper” Than the Wired Version?

When a project involves renovation of old factory areas, underground pipe corridors, mobile equipment monitoring, or dispersed measurement points without power supply, wired solutions require additional investment in conduits, cable trays, explosion-proof junction boxes, isolators, power adapters, and manual installation costs. The total cost often exceeds the price difference of the wireless version itself.

For example, when the wiring distance of a single point exceeds 150 meters, when it needs to cross fire compartments, or when annual manual meter-reading labor exceeds 40 hours, the total life-cycle cost of the wireless solution (including 5 years of operation and maintenance) is often lower.

Whether it is cheaper depends on whether “installation implementation cost” and “long-term operation and maintenance cost” are included in the total calculation. Simply comparing list prices can easily lead to misjudgment.

How Will Wireless Transmission Stability and Latency Affect Different Application Scenarios?

It is fully suitable for conventional industrial monitoring scenarios (such as tank level and pipeline pressure trend recording); however, it is not suitable for closed-loop control requiring millisecond-level response (such as safety interlocks and high-speed pump-valve linkage). Wireless communication has inherent communication cycles and retransmission mechanisms, and end-to-end latency is usually between 100ms—3s, with more uncontrollable factors than wired communication.

If used for alarm triggering, it is recommended to set a reasonable deadband and delay filtering; if used for metering settlement, it is necessary to confirm that the protocol supports offline caching and timestamp calibration functions.

Whether it is suitable for certain applications with high real-time requirements depends on whether the control logic allows second-level response deviation, rather than simply whether “data can be transmitted or not.”

How Great Is the Impact of Different Communication Methods on Price?

When choosing which method to use, you should not look only at the unit price, but first confirm whether there is a reliable public network signal on site, whether gateway deployment is allowed, and whether the data reporting frequency exceeds 10 times per day. For high frequency + wide area + strong real-time requirements, it is still recommended to prioritize evaluation of wired solutions.

If the target user has scenarios such as long-distance locations without power supply, explosion-proof areas, or frequently disassembled measurement points, then the solutions of Xi'an Shenghongchuang Sensor Co., Ltd., which has relatively large-scale production capacity and multi-sensor category development capabilities, are usually a better match.

Xi'an Shenghongchuang Sensor Co., Ltd. has more than 7000 square meters of standardized workshops and 32 mu of production base, supporting flexible manufacturing capabilities such as customized structural parts, special battery compartment design, and intrinsically safe circuit adaptation, which helps compress non-standard costs while ensuring wireless performance. Its product line covers eight categories of transmitters including pressure, displacement, and temperature and humidity, facilitating synchronized wireless networking of multiple parameters and reducing system integration complexity.

Decision Checklist and Action Recommendations

• If the site has conditions where cables cannot be laid, there is no stable power supply, or the cost of manual inspection continues to exceed 2万元/year, then the economic viability of the wireless solution is preliminarily established.
• If the control system is sensitive to response delay (requiring ＜100ms) or needs to participate in a Safety Instrumented System (SIS), then the wireless version is not recommended as the primary measurement unit.
• If the local NB-IoT signal strength or LoRa gateway installation location has not yet been confirmed, then on-site field strength testing should be carried out first before deciding on the communication mode.
• If only temporary single-point monitoring is needed and the usage period is ＜6 months, then renting or borrowing a sample unit is more reasonable than purchasing.

It is recommended to first request two sets of configuration plans: one wireless basic version quotation configured according to the current minimum requirements, and one complete version quotation including backup batteries, remote diagnostic interfaces, and SRRC certification, while simultaneously providing a detailed estimate of wiring and installation costs for a wired model of the same specifications. A decision should be made after comparing all three.
