PTX20 Submersible Pressure Transmitter

Brand: Status Instruments

The PTX20 is a high quality level transmitter providing a 2-Wire (4-20) mA output over a wide pressure range. 

The piezoresistive element provides excellent accuracy and stability in an all welded stainless steel housing. A titanium housing is available on request for more aggressive process media. 

The body of the product is oil filled and coupled with high accuracy electronics, this enables the product to maintain a very high level of accuracy and temperature stability when used with high temperature processes. 

There are open and closed versions to choose from, and also a ballast weight can be specified too. 

Measurement ranges of any value between 1 mH2O to 250 mH2O can be ordered making the PTX20 a very versatile product suitable for many applications.
