Overview
Description
The Model 375 Low Cost Submersible Level Transmitter is specially designed to provide the convenience of direct submergence in many types of liquids for quick, accurate and reliable level measurement. The 375 provides a lower cost, lighter weight option for submersible level applications. The simple design and rugged construction of this solid state instrument provide long lasting service with virtually no maintenance.

The Model 375 Transducer indicates the level of liquid by continuously measuring hydrostatic pressure via its isolated sensing element, an ion implanted silicon semiconductor sensor. The output signal is 4-20 mA. For other input / output options, consult factory. This design provides for excellent linearity and repeatability, low hysteresis and long term stability at an economical price.

The Model 375 is easy to install; simply lower the transducer into a vessel or well. It’s that easy. All the electronics are mounted in a submersible 316 stainless steel housing. A special cable support bracket is also available. This gives extra stability to the transducer when used with longer lengths of cable (up to 2500 feet) or when used in an agitated liquid. A conduit adapter is also available.

A specially designed 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.

The transducer is available calibrated for any span needed, from 6 psi (13.8 ft of water) to 300 psi (692 ft of water)
