DewPro MMY2650 - Trace Moisture Analyzer

DewPro MMY2650 - Trace Moisture Analyzer

 

The MMY 2650 is a moisture analyzer designed to operate with the General Eastern DY5 or DY55 planar gold aluminum oxide dew point sensor. The unit offers an optional input that can be used for pressure compensation, an external temperature probe, or any other sensor this input can be configured to accept 0 to 5 VDC and 4 to 20mA. The standard product comes with one current output (0-20 mA or 4-20 mA), a system alarm relay, and 3 adjustable relays, all with single-pole double-throw 2.5A contacts, selectable failsafe mode, and adjustable hysteresis. One or two additional current outputs are available.

 

The Model MMY2650 is available in both wall mount or panel mount configurations. When used with the DY5 or DY55 Dew Point Probe, the system is capable of providing dew point readings in the range of -80°C to +20°C dew point over a temperature range of -20°C to +60°C. When used with approved Zener Barriers the Model MMY 2650 is approved as intrinsically safe for use in hazardous areas by Cenelec and FM. ATEX approval pending.
