LIT25 Level Indicating Transmitter
- Maximum Range of Sensor
32 ft (10m) - Accuracy
±0.25% of Range - Output
Isolated 4-20mA, 1000 ohm load maximum
This new LIT25 Level Indicating Transmitter displays, controls and transmits level. Mount the non-contacting ultrasonic sensor at the top of your tank and the compact, watertight electronics/display enclosure at a convenient location nearby. Operators can calibrate the LIT25 with its 2-button Keypad, without climbing the tank. Use the built-in relay for level control or alarm, the large 4-digit display for local indication, and the isolated 4-20mA output to transmit level to a PLC.
The standard ultrasonic Sensor measures liquid levels up to 32 ft. (10 m), and includes automatic temperature compensation. Choose the optional all-Teflon sensor for chemical compatibility, or one rated to 50 ft (15.6 m) range. All ultrasonic sensors are available with optional intrinsic safety for installation in hazardous rated locations. The LIT25 can also be ordered with gauge-type pressure sensors for special applications.
