AIC - Model 700 Series -Submersible Liquid Level Transducers
The Series 700 family of submersible liquid level pressure transducers is specifically designed to meet the rigorous environments encountered in liquid level measurement and control. It can be configured to perform to specifications under the most adverse, reactive conditions. These transducers incorporate the latest advancements in piezoresistive pressure sensing technology. A stability enhancing charged "Field Shield" is vapour deposited directly to the pressure cell. A welded 316 stainless steel diaphragm with a spring ratio of 1000:1 with the piezoresistive pressure cell is used for contact with the media. The series 700 also features state of the art surface mount internal signal conditioning which provides a power supply rejection of 0.001% and a 4-20mA process signal.
Each transducer is shipped with a desiccant barrier which prevents moisture from entering the cable vent tube and with a traceable calibration card. An optional aneroid bellows can be fitted instead for the desiccant barrier for applications in which the desiccant tube cannot be replaced.
A range of field installable nose caps are optionally available. The open faced nose cap is supplied as standard and is ideal for wastewater and greasy applications where clogging of the sensor is a concern, the closed face nose cap is best used where sharp protruding objects may be encountered. The 1/4" NPT nose cap can be used for calibration and also allows the sensor to be used as either an in line or submersible sensor.
The Piezometer nose cap allows the unit to be buried in the ground without damage to the sensor diaphragm.
Typical applications include well monitoring, pump control, ground water monitoring, soil remediation, oceanographic research, lift stations, level monitoring & control and surface water monitoring.
The transducer is certified intrinsically safe. When installed in hazardous areas approved electrical barriers must be used and local & national electrical standards adhered to.
