Function

The TP-140D measuring pressure transducer (hereinafter transducer) is designed for operation in various industries, automatic process control systems to ensure continuous transformation of excess pressure of neutral and aggressive environments into unified current output signal 4…20mA. The transducer is powered through a two-wire power supply/communication line.     

The transducer complies with GOST 22520-85 "Pressure, vacuum and pressure difference transmitters with electrical analog output signals, SSI. General specifications".

The transducer can operate in an explosive atmosphere. Explosion safety is ensured with the help of a spark-safe electric circuit. The explosion protection level of the transducer is "ib" due to the spark-proof design of a power unit or an IS barrier.  

The transducers are designed for operation with secondary recording or indicating equipment, regulators and other automatic devices, centralized control machines and control systems receiving standard dc signals 4...20mA.
