igh Precision Digital Diffused Silicon Pressure Transmitter
Product Overview
This pressure transmitter adopts advanced diffused silicon pressure sensing chip, with two mainstream signal output options: 4-20mA analog signal and RS485 digital signal. Equipped with optional 4-digit 8-segment digital display, it can real-time show measured pressure value. It is widely applied to measure water pressure, gas pressure, oil pressure and hydraulic pressure in water treatment, chemical, power, pneumatic and constant pressure water supply systems. Multiple measuring ranges and specifications are available to meet different industrial testing scenarios.
Core Product Advantages
High Precision Diffused Silicon Sensing CoreClassified temperature drift control: 2%FS for range 10kPa~60kPa, 1.5%FS for range 60kPa~60MPa within compensation temperature zone, ensures stable accurate reading under temperature change.
Two Optional Signal Output Modes
4~20mA analog output: Power supply 17~32VDC, with 4-digit digital display tube
RS485 digital output: Power supply 5~28VDC, 4-digit real-time pressure display
Ultra-Wide Temperature Adaptability
Working & medium temperature: -20 ~ 85℃
Storage temperature: -40 ~ 85℃
Segmented temperature compensation range from 0~60℃ up to -10~70℃ according to measuring range, fit indoor and outdoor industrial environments.
Reliable Overload Protection
0.035MPa ~ 10MPa range: 150%FS overload withstand capacity
10MPa ~ 60MPa high pressure range: 125%FS overload resistance, avoid sensor damage by sudden pressure surge.
Complete Range SpecificationsStandard ranges in stock: -100~0kPa vacuum, 0-10kPa, 0-50kPa, 0-0.6MPa, 0-1MPa, 0-1.6MPa, 0-60MPa; custom measuring ranges are supported.
Wide Industrial CompatibilityStainless steel pressure interface, standard thread connection, easy to install on pipelines, pumps, hydraulic stations, air tightness test benches and water supply equipment.
