LM * 316L SS Pressure Sensor with PVC Threads * Small Profile * 0.5 - 4.5V High Level Output * Gage * ASIC Calibrated DESCRIPTION The LM Series incorporates stainless steel and plastic isolation suitable for level sensing in water and other liquids. The LM series uses a patent pending low cost stainless steel sensor in a PVC plastic fitting. The modular design is adaptable to an infinite number of plastic port variations. With high performance in a small form factor, the LM Series enables the miniaturization of high accuracy pressure systems. The standard output is .5V to 4.5V with a 5V supply.
