The Model SST Level Transmitter indicates the level of liquid by continuously measuring hydrostatic pressure via its sensing element. The SST was designed for small bore applications, weighing only 8 oz. with an outside diameter of only 0.69 inches. Once the sensor measures the pressure, the data is transmitted by a 4 to 20 mA two wire output signal. This design provides for excellent linearity and repeatability, low hysteresis and long term stability.
