The low-cost
submersible level transmitter is designed specifically to provide the
convenience of direct submergence in many types of liquids for quick, accurate and
reliable level measurement. The simple design of the unit ensures long-lasting
service with virtually no maintenance. Transmitters indicate liquid level by
continuously measuring hydrostatic pressure via its isolated sensing element—an
ion implanted silicon semiconductor chip with integral Wheatstone Bridge
circuit. Once the sensor measures the pressure, the data is transmitted by a 4
to 20 mA output signal. This design provides for excellent linearity and
repeatability, low hysteresis and long-term stability at an economical price. The
unit is easy-to-install. Simply lower the transducer into a vessel or well. All
of its electronics are mounted in a submersible 316 stainless steel housing. A
special cable is factory installed and sealed to insure liquid tight
performance. The customer connection end of the cable is sealed and a desiccant
package is installed to limit the amount of moisture allowed to enter the
barometric reference of the sensor. Other options are also available.
