雙路M70濕度分析儀預處理

產品簡介：
This uniquely rugged and simple design by Envent Engineering utilizes a heated conductive polymer sensor that provides a linear output of the moisture concentration in a natural gas stream.

雙路M70濕度分析儀預處理

產品特點：
Range: 0–20lbs/mmscf (custom ranges available) 
Rugged mechanical design 
Affordable measurement 
Data logger 
Unit will display in lbs/mmscf and/or ppm 
2% of reading or 10 ppm (0.5 lb per million) accuracy 
4–20 mA output and alarms (2-wire) 
RS-232 and RS-485 Serial Communications 
Ultra-low power: Less than 2 watts power consumption 
Dual-line, 16-character display 

Value
The unit has a 4–20 ma output and RS-232/485 serial communications, alarms, internal menu scroll buttons. The M70 can display up to 128 different parameters including lbs/mmscf, ppm, sensor temperature, raw millivolts and calibration factor and sensor heater load. The sensor is mounted in an insulated flame proof enclosure with flame arrestors installed in the sample flow path. Many natural gas tariff limits are set a 4 lbs water per million standard cubic feet. This is closely equivalent to 80 ppm or 64 mg/m3. The sensor is controlled to 50?C and operated at atmospheric pressure to maximize resistance to process variables and adsorption of stream contaminants.

Foul resistant. The M70 offers industry leading value in price while still maintaining reliability. The rugged sensor is resistant to chemical fouling such as amines and glycols and methanol and can be washed with alcohol without permanent damage.

Minimal Power Removable Sensor. The sensor can be readily removed for cleaning or replacement with standard tools in seconds. The linear output enables the user to perform a single-point calibration. The standard M70 uses less than 2 watts power when installed in areas where ambient temperature is more than 0?C. This means it can be used at sites where only solar or other minimal power is available.
