Model CLTX-420A Continuous Level Transmitter operates with vertical mounted, stainless steel float sensors that are ideal for monitoring liquid height in many applications. The sensor/transmitter combination accomplishes tank level measurement by providing a current or voltage output that corresponds the position of the float as it travels up and down the sensor’s shaft. Connect the transmitter output to a process meter or PLC to control a pump, valve or alarm unit. These sensors are rugged, reliable and available in a wide variety of lengths to 60”.
