XNX Universal Transmitter
MPD (Multi Purpose Detector)
Similar to the transmitter, the MPD part numbering system defines
the agency approval and thread type (i.e., port configuration).
The only material selection is stainless steel. Four sensor types
are available. Agency approvals are specific to these four sensor
types (see Sensor Data). Ensure that the approval of the sensor
type meets the requirements of the installation.

1. Agency approved hydrogen sensors are MPD-CB1 and 705 STD.
2. When ordering replacement MPD sensor cartridges, the replacement cartridge must be the same type as factory configured. Substituting a different cartridge will void agency
certification.
3. On XNX %LEL units carrying UL/CSA certifications, the range is fixed at 100%LEL and is not adjustable.
4. Humidity: 5% to 95% RH non-condensing
5. Humidity: 0 to 99% RH non-condensing
