Analysis of Common Selection Issues for Diffused Silicon Hysteresis Pressure Sensors

Is the measurement range of the BP-IB pressure transmitter insufficient? The selection of a diffused silicon hysteresis pressure sensor directly affects measurement accuracy. As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang Instrumentation analyzes the technical parameters and selection points of models such as PTS501 and AO-X for you, helping operators solve common issues such as insufficient measurement range and accuracy grade selection.

In the field of industrial process control, the measurement range of a pressure transmitter directly affects the operational stability of the system. Taking the BP-IB model as an example, when continuously low measured values or over-range alarms occur, they are often directly related to improper sensor selection. This article systematically analyzes the matching principles of key parameters such as measurement range and accuracy grade based on the technical characteristics of diffused silicon hysteresis sensors.

I. Root Cause Analysis of Insufficient Measurement Range

1. Improper range selection: When the actual working condition pressure peak exceeds 80% of the sensor's calibrated range, nonlinear error will increase. For example, in hydraulic control system applications, the TMS-GH186 pressure transmitter requires at least 20% overload margin.

2. Impact of medium characteristics: Corrosive media can change the strain characteristics of diffused silicon sensors. The domestic general-purpose pressure transmitter TV510 intelligent vacuum pressure sensor using a 316 stainless steel diaphragm performs more stably in the petrochemical industry.

3. Insufficient temperature compensation: The temperature drift of the BP-IF model in high-temperature environments can reach ±0.05%FS/℃, and a version with wide-temperature compensation (80-70℃) should be selected.

II. Interpretation of Core Technical Parameters of Diffused Silicon Sensors

Special attention should be paid to the wiring differences of the BP-IE pressure transmitter: the two-wire system (4-20mA) is suitable for long-distance transmission, while the three-wire system (0-10V) is more suitable for short-distance connections inside cabinets.

III. Selection Guide for Typical Application Scenarios

1. Hydraulic systems: It is recommended to select the YH-A series model with a G1/4 threaded connection, whose rise time ≤5ms can meet the needs of dynamic pressure monitoring.

2. Constant-pressure water supply: The BP-IN pressure transmitter used with a ceramic piezoresistive sensor can avoid zero-point drift caused by the water hammer effect.

3. Petrochemical industry: The TMS-QY110 with a fully welded 316 stainless steel structure should be selected. Its medium-contact part is designed without an O-ring, eliminating leakage risk.

IV. Troubleshooting and Maintenance Key Points

When the BP-IB pressure transmitter displays abnormalities, troubleshooting should be carried out according to the following steps:

1. Check whether the supply voltage is within the 9-36VDC range
2. Use a multimeter to measure whether the output current is within the 4-20mA range
3. Verify the range parameter settings of the ZFBY3801 pressure transmitter
4. Perform zero-span/full-scale calibration (adjustment range ±8%)
