As core technical equipment in the field of pressure measurement, the TY-804 pressure transmitter adopts a high-precision diffused silicon sensor and is widely used for liquid and gas pressure detection. This article explains in detail its specifications and models, accuracy grades, and common fault handling, helping operators correctly select and use PT124B-213, P-P900, and other series products to solve practical issues such as calibration and display.

I. Technical Principles and Industry Applications of Diffused Silicon Sensors

The diffused silicon pressure sensor is based on the piezoresistive effect principle and realizes pressure measurement through resistance changes in semiconductor silicon chips. Compared with traditional strain gauge technology, its sensitivity is increased by 5-10 times, and temperature drift can be controlled within ±0.05%FS/℃. In harsh working conditions such as hydraulic control and petrochemicals, Domestic General-Purpose Pressure Transmitter AT-131 LCD Display Negative Pressure Pressure Sensor uses 316 stainless steel wetted material, can withstand up to 250MPa high pressure and 85℃ medium temperature, and meets the measurement requirements of corrosive media for models such as JPB-JPB2300.

II. Comparative Analysis of TY-804 Core Parameters

Through comparison, it can be seen that TY-804 has obvious advantages in measurement range coverage and signal output diversity, and is especially suitable for scenarios requiring wide-range applications such as CS-PT300. Its Class 0.25 accuracy can meet the high-standard requirements of YB-YB3011 for laboratory calibration.

III. Selection Guide and Common Problem Solving

Three Key Factors for Selection:

• Medium type: corrosive media require 316 stainless steel material
• Pressure range: it is recommended to select an upper measurement limit that is 1.5 times the actual operating pressure
• Accuracy requirement: process control usually selects Class 0.5, while metrological verification requires Class 0.25

Typical fault handling:When HH-HH316 shows abnormal display, first check whether the 24V supply voltage is stable; if the PT-PT202 output signal drifts, calibration can be performed through the zero-point adjustment function, with an adjustment range reaching ±8% of the measurement span.
