Honeywell Sensepoint XCD Explosion-Proof Transmitters SPXCDASMTX4SPXCDASMRXM

Sensepoint XCD-RTD transmitter (use with oxygen and toxic Sensepoint sensors)

Sensepoint XCD-RTD (Remote Toxic Detector) allows for a gas sensor from a wider selection of 2-wire 4 to 20mA input type Toxic and Oxygen sensors to be fitted directly to the transmitter housing, or wired remotely from another location.
KIT includes Transmitter, Magnetic Wand and Allen Key

Sensepoint XCD 
Transmitter provides comprehensive monitoring of combustible, toxic and Oxygen gas hazards in potentially explosive atmospheres – indoors and outdoors.

Features & Benefits

  • All-in-one gas monitoring solution
  • Proven SurecellTM electrochemical sensors
  • Global approvals

Quick Specs

  • Input voltage range: 16 to 32 VDC (24 VDC nominal)
