The MMT338 enables fast and reliable detection of moisture in mineral based transformer oil. It primarily measures the moisture of the oil as water activity (aw), but in this version the reading is converted into a ppm output calibrated for mineral-based transformer oils.
The probe can be inserted (and removed) directly into the lubrication oil through the supplied ball valve without draining the system.
The transmitter has a keypad and a large graphical display for convenient monitoring of the reading and transmitter setting changes. For example both output signal type (voltage or current) and scaling can easily be changed by the user.
Analog outputs are preset at the factory to:
Channel 1: 4…20 mA = 0...100 ppm
Channel 2: 4...20 mA = -40...+180°C (-40...+356°F) T
The package includes:
Pressure tight probe with 5 m (16.5 ft) cable
Calibration certificate (ISO9001 compliant, traceable to NIST)
Ball valve set with welding joint
ISO1/2" and NPT1/2" pressure fittings for probe installation into pipeline or pressure vessel
M20x1.5 cable gland and NPT1/2" conduit fitting included to facilitate wiring
