United Electric Controls announces upgrades to One Series of programmable transmitters

June 7, 2016 United Electric Controls, a producer of temperature and pressure switching technology, announced today an upgrade to its One Series line of explosion-proof, programmable transmitters and switches. The upgraded line compresses all of the functionality of the preceding line into five models while adding new operational, programming and diagnostics capabilities.

United Electric Controls One Series instruments are designed to provide unique alternatives to both conventional mechanical switches and transmitters for controlling operations such pumps and compressors, lubrication oil monitoring, hydraulic pressure, filter status and other industrial applications based on temperature or pressure. The One Series line offers these advantages by providing switch only, transmitter only and hybrid transmitter-switch models.

Customers choose from among the following new One Series instruments based on their requirements for integrated switching and sensing, intrinsic safety, power level and power source.

  • For integrated switching and transmitter, model 1XTXSW provides a loop-powered 24 VDC HART enabled smart-transmitter, with two programmable set point fail-safe solid state relays rated at 0-280 VAC/VDC @ 0.3 A.
  • For high voltage, low current switching only, model 1XSWHL provides a 2-wire input powered switch for 110 and 230 VAC and 125 VDC logic solver inputs, with a programmable set point switch rated at 70 – 240 VAC/VDC at 0.1 A max.
  • For low voltage, low current, intrinsically safe switching only, model 1XSWLL provides a 2-wire input powered switch for 24 and 48 VDC logic solver inputs, with a programmable set point switch rated at 7.8 – 50 VDC at 0.1 A max.
  • For high voltage, high current  switching only, model 1XSWHH provides a 4-wire externally powered programmable set point switch rated at 70 – 240 VAC @ 0.15 - 10 A
  • For use as a transmitter only, model 1XTX00 provides a loop-powered 24 VDC HART enabled smart transmitter compliant to the NAMUR NE 43 standard.

Both of the 2-Wire input powered switch models mentioned above (model 1XSWLL and 1XSWHL) utilize existing wiring and control schemes and can provide a drop-in replacement for mechanical switches. No wiring or control system programming changes are required.

All One Series models have diagnostics, programmability and trip management capabilities. Configurable I Am Working (IAW) self-diagnostics provide piece of mind that the instrument is functioning properly by communicating with the control system using a discrete fail-safe-open output. The integral digital process display shows what is happening in the process. Plugged port diagnostics flag potentially dangerous sensor clogs and memorizes the highest and lowest process variables for process troubleshooting and learning.

A programmable set point and deadband provides alarm and shutdown switching using the integral keypad.  HART® enabled models provide full access and control of all transmitter and switching functions using any registered HART communicator.  A programmable trip delay, which holds off the trip decision for tenths of seconds up to several minutes, provides operators time to gather more data before initiating a shutdown.
