Pressure transmitters for low pressures LOPRES LP1000, from ESI
The LP1000 series pressure transmitters are designed to measure very low pressures, with a minimum range of 0...50 mbar without sacrificing performance. The advanced cell design provides very low hysteresis and excellent long-term stability, which is rarely the case when measuring low pressures. Thanks to the combination of the stainless steel body, the nitrile O-ring and the stainless steel measuring element, the transmitters of the LP1000 series are suitable for measuring most fluids in the range of 0 to 100 mbar and more. . For pressures below 100 mbar, the stainless steel measuring element is replaced by a silicon sensor, ideal for non-corrosive gases and various silicon-compatible liquids. These transmitters are particularly precise and stable over time. Available for pressure ranges from 0...50 mbar to 0...500 mbar, and with analog output type 10 mV/V, 0 – 5 V, 0 – 10 V or 4 – 20 mA. The spectrum of applications includes laboratories and test centers and clean rooms, air and gas pressure control, leak detection and low hydrostatic pressure measurements.
