PTX20-serien

Submersible pressure transmitter with ATEX option

The PTX20 is a submersible pressure transmitter providing a 2 wire (4 to 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 0.5mH2O to 250mH2O can be ordered making the PTX20 a very versatile product suitable for many applications.

SUBMERSIBLE PRESSURE TRANSMITTER FEATURE HIGHLIGHTS

TANK LINEARISATION (with SEM1600VI)
When used with products like the Status Instruments SEM1600VI conditioning block (the SEM1600VI can
also provide power for the PTX23) a user non-linear curve can be applied to the (4 to 20) mA signal to allow
for volume measurement in non-linear shaped tanks.

WEIGHTED OPTION
A weighted option is available for use in flowing or turbulent applications to help keep the PTX23 in place.

ALARM RELAYS (with SEM1636)
When the PTX23 is used with products like the Status Instruments SEM1636 (4 to 20) mA loop powered
alarm, two independent alarm trips can be used. The SEM1636 can also be linearised for non-standard
tankar
