M Series Pressure Transmitter
Featuring Type 4 Certification
The M Series family of differential pressure transmitters measure low pressures and feature a wide variety of analog signal outputs with low power consumption. A wide selection of standard pressure ranges and electrical ratings is available. These transmitters feature: no moving parts to wear out, reliable long term stability, and are virtually position insensitive.
Series M transmitters are typically used for monitoring cleanroom pressures, HVAC, velocity pressures, bubbler level systems, and leak detection; as well as filter differential, draft, fume hood and other low pressure applications.
The transmitters are housed in a compact heavy duty gasketted cast aluminum enclosure designed to IP 65 of IEC 529 standards and NEMA 4. The die cast aluminum enclosure incorporates a recessed neoprene gasket to prevent ingress of moisture or dust. Wall mounting holes are enclosed in the cast aluminum box and concealed by the cover. The wall mounting holes and the cover attaching screws are outside the gasketted area. Access to the terminals are made through knockouts on the front of the box. A choice of one or two knockouts and three hole sizes is available to accommodate usage of 1/2 inch conduit and metric sizes PG11 and PG13. Pluggable terminal block connectors are provided with captive wire protection and captive terminal screws.
The Series M includes four models: Model M10, Model M20, Model M30 and Model M40. These four models incorporate a variety of power and signal options. The span or zero adjustment is performed with a 20 turn potentiometer for fine resolution. The M Series transmitters have been tested by an accredited laboratory and comply with the European requirements of Council Directive 89/336/EEC for emission measurements per EN50 081-1 and immunity tests per EN50082-1.
