LP1000 series now extends the pressure sensor technology into very low-pressure applications, with operating ranges down to 0-50mbar while maintaining high performance. The advanced sensor design provides very low hysteresis and excellent long-term stability not normally achievable when measuring very low pressure.
The LP1000 offers a low cost solution for accurate measurement of very low pressures and is specifically designed for use in media such as air, non-corrosive gases and various liquds compatible with silicon. The stainless steel housing, fluorosilicone seals and silicon sensing element enables the product to maintain accurate performance and provide extremely good durability.
Available in pressure ranges from 0-50mbar to 0-1000mbar and with electrical outputs of 0-100mV, 0-5VDC, 0-10VDC, and 4-20mA.
Application include laboratory and test air and gas pressure monitoring, leak detection, low pressure liquid and hydrostatic measurements.
