The DewPro MMY31 is a loop-powered dew point transmitter for in-line trace moisture measurement in gases, using a planar aluminum oxide sensor. It mounts directly with 1/2 in. NPT-M, 3/4 in. NPT-M, 3/4-16 O-ring, or G 1/2 compression fittings and has a 316 stainless steel probe with 2 to 3.5 in. adjustable insertion length. It measures dew point from -130°F to 50°F (-90°C to 10°C) with ±3.6°F (±2°C) accuracy at 77°F (25°C) and supports process pressures up to 1750 psig (120 bar). Output is 4 to 20 mA with 16 μA resolution, powered by 12 to 30 VDC. The enclosure is Type 4X/IP67. An optional integrated display provides programming and diagnostics. It is FM-approved for intrinsically safe and explosion-proof use in Class I, II, III, Division 1 and 2 hazardous locations and complies with EMC Directive 2014/30/EU and PED 2014/68/EU. Weight is 3.3 lb (1.5 kg).
The DewPro MMY31 measures dew point or ppm in gases. It is a cost-effective, loop powered dew point transmitter designed for "in-line" installation where trace moisture measurement is required. The planar aluminum oxide sensor provides excellent corrosion resistance, longer calibration stability, quick response times, and an exceptionally low temperature coefficient.
The DewPro MMY31 mounts directly in-line in your process gas, where a bypass installation is not appropriate. It is easily installed via a variety of adjustable insertion length compression fittings. The optional integrated display with user interface provides full programming and diagnostic capability.
Applications include glove boxes, environmental chambers, test chambers, and other locations where direct insertion is required.
