Self-contained Dew Point Instrument for Easy Installation

Jul 30 2008

The DryCheck dew point instrument has been launched by Michell Instruments (UK) as a response to demands from customers for an accurate, stable but economic instrument, with simple sampling system, which could be easily installed for use in a number of dew point measurement applications.
All components are housed in a rugged IP65 rated polycarbonate case. This can easily be wall mounted at a convenient point close to the gas sample.
A clear cover protects the display and the sample flowmeter. Gas connection (gas in and gas out) is provided using “quick connect” push-fittings, suitable for use with 6 mm OD Teflon tubing. Mains power input, and connection to the 4-20 mA analogue output, and the two user programmable voltage free relay contacts are all easily accessible behind the lower panel.
The DryCheck utilises the Michell Instruments Easidew On-Line to measure dew point in the range –100 to + 20*C dew point, or moisture content in the range 0-3000 ppm. This well-proven instrument has at its heart, Michell`s advanced Ceramic Moisture Sensor providing accurate and stable measurement.
The calibration data for each sensor is stored within the transmitter`s flash memory. This allows Michell Instruments to offer the unique sensor exchange scheme, keeping calibration costs and downtime to an absolute minimum.
The DryCheck sampling system includes a 0.3 micron particulate filter element, a monolithic sampling block to house the Easidew Transmitter, and a valve and flowmeter for setting the sample flow. The filter element is easily replaceable to ensure that the sensor is protected. All components are rated to 10 Barg and the DryCheck can be configured for measurement of dew point at either system or atmospheric pressure.
The DryCheck features an extremely clear 20 mm red LED display, which can be programmed to display dewpoint, in *C or *F and moisture content in ppmv. The instrument also provides a 4-20 mA output and 2 off alarm relays. All these features are easily configurable by the user via the front panel of the display, making DryCheck one of the most versatile
instruments on the market.
The DryCheck is the perfect choice for measurement of dew point or moisture content. Specific applications include compressed air dryers, ozone generators, plastic moulding machines, industrial gas manufacture and supply and many more.
