PTS30 series Dial Plate Pressure Transmitter

Characteristics: Smart digital pressure measurement instrument: flexible to use; easy to regulate and the operation is simple. The appearance is exquisite, and having smart menu and the function of self-correction, and self-diagnosis. Having vertical PTS31 and embedded PTS32, can satisfy different demand. It can replace the pressure gauge totally, having the analog function, equipped with remote output contact.


    PTS30 dial-type pressure transmitter is a multifunction product which is integrating the pressure measuring, display, control in one. It is an intelligent digital pressure measuring instruments: flexible to use, easy to regulate, and the operation is simple. The display screen adopt the way which the main screen and the vice screen showing at the same time. When working, the main screen shows the parameter values, and the vice screen shows the control word of the parameters. Every control output contact includes 1 normally open contact, 1 normally close contact and 1 alarm indicator. At the same time, it can deploy the most 5 alarm control contact and 4--20mA standard current output according to the user's requirements. If you have special demand, we can also make it.
