‘No-foul’ level transmitters with diaphragm

Keller, leading manufacturer of measuring technology such as isolated pressure transducers and transmitters - represented in southern Africa by Instrotech – offers a specifically designed level transmitter with Kynar®-Diaphragm for sewage applications (non-fouling) for extended service in sewage lift station environments.   Keller’s 36XKY features a relatively wide monolithic diaphragm yet small overall size, combining the non-stick quality of Teflon with superior toughness and abrasion resistance that simplifies installation and eliminates the need for bulky and expensive protective cages.

The 36XKY uses proven piezo-resistive silicon measurement technology combined with Keller’s state-of-the-art, microprocessor-based signal conditioning circuitry to provide high accuracy and reliability over a wide compensated temperature range.  It is ideally suited to pump control applications that require standard 2-wire (4...20 mA current loop) or 3-wire (0...10 V) output transmitters. The RS485 interface allows users to scale the analog output to any desired range within the standard pressure range. The 36XKY is typically suspended into the liquid by a standard Hytrel®-jacketed cable that is both self-supporting and vented.  Keller’s enhanced lightning protection makes this transmitter ideal for installation in areas prone to chronic damage due to transients caused by lightning.

Using the Keller CCS30 software and appropriate adapter cable, the user can scale the analog output of the 36XKY, display and record pressure and temperature readings, and access a variety of other available functions. All of the available functions are defined in the Series 30 Communications Protocol. The CCS30 and Series 30 Communications Protocol are available free of charge.

The 36XKY has benefits such as:

  • Non-fouling diaphragm design
  • Housing resist chemical attack (AISI 316L)
  • Digital interface RS485
  • Rangeable analog output
  • Mathematically compensated
  • Increased reliability in lightning-prone regions

Instrotech – a Comtest Group Company - distributes and manufactures a range of process control instrumentation and specialised systems which are sold locally and internationally through a number of designated distributors.
