The LD30 general purpose external mount pressure level transmitter provides continuous liquid level measurement up to 34.65’ (10.5m) of water column with a 4-20 mA signal output. Offered in two level measurement ranges and termination types, select the -S_01 model for cable termination or the -S_11 model for M12 connector termination. The LD30 pressure level sensor is well suited for clean liquids compatible with 316 SS such as process water and diluted chemicals.
External Mount:
The externally mounted pressure sensor provides a simple, low-cost, level measurement solution for metal tanks, and is easily installed via a 1/4” tee or tap fitting located in the tank’s drain or inspection port.
