HygroPro-MMY150DY55

Hygrotec MMY150 / DY55 Trace Moisture Analyzer

The Hygrotec( MMY 150 provides economical trace moisture analysis system for dew point in specialty gases and dry air. It consists of an MMY 150 transmitter and DY 55 probe. The probe utilizes a proven, planar capacitive sensor for fast response times, corrosion-resistance, calibration stability, and a low temperature coefficient. The probe converts the capacitance into a standardized PFM signal and transmits it to the MMY 150. Process moisture is controlled with one current output, one voltage output, two alarm relays, and one system alarm relay.

The MMY 150 is a stand-alone, single-channel analyzer that measures dew point temperatures from -100·C to +20°C (-148°F to +68°F) with ( 2°C ± 3.6°F) accuracy. The analyzer includes a four digit LCD display and analog bar graph. The microprocessor-controlled analyzer displays dew point temperature in °C, or, optionally, in ppmv. This optional version can also communicate with an external computer to provide multi-channel configuration or integration with other process analyzers. The MMY 150 mounts in a 19” rack mount, a panel mount or a wall mount enclosure with 230/115 VAC power supply.

Features:

Cost-effective, flexible trace moisture analyzer with dew point and optional ppmv display

Dew point measurement range of -100°C to +20°C with ±1°C accuracy

Interference-free PFM signal transmission

Compact, 7 pitch (35 mm) module

Standardized, programmable probe output signal; with three alarms

ACKBUS compatible
