IECEx Explosion Proof Indicator

for 4 to 20mA input

This loop powered, digital, explosion proof indicator is IECEx approved to Ex d IIC T6 Gb (Gas) and Ex tb IIIC Db (Dust) for zone 1 use. Processes variable from any 4~20mA current source can be monitored. No additional power supply or wiring is needed as the unit derives its power from the loop. It can be incorporated into almost any 2 wire loop where local or remote indication is needed due to a low voltage drop (5 Volts at 20mA). With a 4 to 20mA input signal, the 4 digit display can be configured to read from -999 to 9999. The indicator can be mounted directly to our thermocouple & RTD sensors or alternatively wall/pipe mounted using the mounting brackets shown below. The decimal point location and engineering units are adjusted using membrane switches.

  • IECEx approval to Ex II 2 GD Ex d IIC Gb (Gas) and Ex tb IIIC Db (Dust)
  • As standard, supplied as a IP68 rated die cast alloy enclosure. 316 Stainless steel option also available
  • Designed for use with local or remote indication of 4~20mA signal. Unit can be mounted to a wall or pipe via mounting options
  • If necessary, a 4~20mA output transmitter can be accomodated
