Product details
PTH705explosion-proofPressure transmitterAdopting internationally advanced high-precision and high stability sensors, coupled with ASIS high-performance amplification circuits, it is refined through thousands of fatigue impacts, high and low temperature cycle aging, and precise digital temperature compensation processes, and then fully sealed stainless steel welding (laser welding).
High quality sensors,Integrated structure, the sensor tail adopts threaded connection, which is convenient for connecting with other devices in the system as a whole, suitable for pressure measurement and control with explosion-proof requirements.The strict verification process and perfect assembly process ensure the excellent quality of the product. It is particularly suitable for measuring the pressure of hydraulic, pneumatic and other media, and even for harsh environments such as sewage, steam, mild corrosiveness, and gas measurement. Build a foundation to meet various customer needs.
