Submersible Pressure Transmitter PTX23

The PTX23 submersible pressure transmitter is built for use in aggressive media, with a stainless-steel piezoresistive sensing element protected by a PVDF outer housing designed to withstand immersion in most aggressive chemicals and waste water. The oil-filled assembly delivers a robust, high-accuracy 2-wire 4-20mA output and is supplied with a choice of PUR or PTFE cable to any required length, making it a proven choice for depth and level measurement in corrosive liquids.

A weighted option keeps the PTX23 correctly positioned in flowing or turbulent applications, and when paired with a Status SEM1600VI signal conditioner it can be linearised for non-linear shaped tanks, or with a SEM1636 loop-powered relay it can drive two independent alarm trips directly from the 4-20mA signal, extending its use well beyond a simple level sensor.

  • Aggressive Media Construction — Stainless-steel sensor protected by a PVDF housing for submersion in aggressive chemicals and waste water.
  • 2-Wire 4-20mA Output — Standard current loop output for straightforward integration into existing control systems.
  • Custom Cable Length — Supplied with PUR or PTFE cable cut to any required length.
  • Weighted Option — Available for flowing or turbulent applications to keep the sensor correctly positioned.
  • Tank Linearisation Ready — Pairs with the SEM1600VI to linearise output for non-linear tank shapes.
  • Alarm-Ready — Pairs with the SEM1636 loop-powered relay for two independent alarm trips from the same signal.

What is the PTX23 designed for?

It is a submersible pressure transmitter designed for depth and level measurement in aggressive chemicals and waste water.

What is the PTX23 made from?

A stainless-steel piezoresistive sensing element protected by a PVDF outer housing, with PUR or PTFE cable options.

Can the PTX23 be linearised for non-linear tanks?

Yes, when used with a Status SEM1600VI signal conditioner, a non-linear curve can be applied to the 4-20mA output for volume measurement in irregularly shaped tanks.

Can the PTX23 drive alarm relays?

Yes, paired with a SEM1636 loop-powered relay it can provide two independent alarm trips directly from the 4-20mA signal.
