PTX 23

Corrosive media transmitter with ATEX option

• Chemical resistant level transmitter made of PVDF
• This transmitter has an excellent resistance to most aggressive chemicals
• Optional over voltage protection
• Reverse polarity and short circuit protected
• ATEX option

Submersible pressure transmitter PTX23, is a high accuracy, robust, 2 wire (4 to 20) mA current output pressure sensing device designed to withstand immersion in most aggressive chemicals. It is an assembly containing a piezoresistive element, oil filled and sealed in a PVDF case with a choice of PUR or PTFE cable to any length required.
The PTX23 submersible pressure transmitter is ideal for applications measuring depth and levels in aggressive fluids, chemicals and waste water. There is also an ATEX version for hazardous area measurements.

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.

FOR USE IN AGGRESSIVE MEDIA
The PTX23 is constructed with a stainless-steel body, protected by a PVDF housing. For use in many
applications where chemical resistance against submersion in aggressive liquids is required.
Please check the suitability of PVDF for use with the intended media.

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
tanks
