61-0230: LEL, MPS type sensor, 3/4 inch NPT 61-1020: LEL, Direct Connect, MPS type detector with XP J-Box 65-2380:LEL, S2, MPS type sensor/transmitter/XP J-Box 65-2650: LEL, M2A, MPS type sensor/transmitter with J-Box
Utilizing a new sensor technology, the MPS (Molecular Property Spectrometer) sensor internally identifies the gas or gases being detected, and applies the appropriate LEL conversion factor so that it will read a variety of flammable gases or vapors correctly by just utilizing a methane calibration. Other sensor technologies, such as catalytic or IR sensors, require a conversion factor to be applied during calibration or that it needs to be calibrated to the specific gas desired to be detected. This is not the case with the MPS sensor. Capable of detecting over a dozen different combustible gases simultaneously, including Hydrogen, the Molecular Property Spectrometer is unsurpassed in reliability, accuracy, and worker safety. No other sensor can match the accuracy of the MPS in reporting 0-100% LEL across multiple gases. The MPS’s robust design means it won’t drift, decay, or poison over time. Expected sensor life is over 10 years in normal applications.
Applications
Applications where silicone is present
High humidity applications where IR or catalytic may not hold up
Applications where a mixture of hydrocarbons could be present

Compatible Transmitters
M2A
The M2A model is an explosion proof transmitter that can operate as a standalone system or as part of a system connected with an analog or digital signal to a controller, PLC, or DCS. The M2A-XL utilizes a magnetic wand technique for performing non-intrusive calibration. The housing does not need to be opened for zeroing or calibration.
Direct digital readout
Explosion proof housing
Operates independently or with any controller, PLC or DCS
4-20 mA transmitter
igital Modbus output
Operates from 10-30 VDC
2 programmable alarm relays, plus fail relay
Auto zero drift correction
Non intrusive calibration via magnetic wand

S2 Series
The Direct Connect sensors can be used in two different ways. The sensors can be mounted directly to the controllers as a complete stand alone system, or they can be mounted to explosion proof junction boxes for remote detection. The plug-in design allows quick replacement in the field with no tools required. The Direct Connect sensors can be used either indoors or outdoors. The flame arrestors utilizes a patented coating, which makes it water repellent.
