S Detector Non-Explosion Proof

The construction of the various ESM-01 detectors is similar. Each of the ESM-01 detectors

has a different replaceable plug-in sensor that protrudes through the detector housing

cap. Although ESM-01 detectors look the same except for the plug-in detector, the detector

housing which includes the detector socket and conditioning circuitry is specific to a

sensor type. For example, a detector housing from a Cl

detector cannot be used with an

detector. One of the two detector wires is color coded for each specific detector type.

The ESM-01 detectors include a removable splashguard that screws onto the detector

housing cap. When it is necessary to apply gas to an ESM-01 detector, remove the

splashguard to allow access to the sensor that protrudes through the detector housing cap.

You can then push the appropriate ESM-01 calibration cup onto the sensor.
