Technical Data
Description
The LP1000 series now extends pressure sensor
technology into very low-pressure applications,with operating ranges down to 0-50 mbar whilst
still maintaining high performance. The advanced
sensor design provides very low hysteresisand excellent long-term stability not normallyachievable when measuring very low pressure.
Offering a low cost solution for accurate measurement at low
pressures, the LP1000 is designed for use with a wide varietyof liquids and gases compatible with 316L stainless steel andnitrile (NBR). It features a robust stainless steel housing offering
reliable performance in demanding applications and is available

with a wide selection of process and electrical connections
options.
Available in pressure ranges from 0-50 mbar to 0-1,000 mbar
and with electrical outputs of 0-100 mV, 0-5 Vdc, 0-10 Vdc andQ%>IVSERHWTERTSXIRXMSQIXIVWEVIEGGIWWMFPIJSV½RI
adjustment of calibration if required.
Applications include laboratory and test, air and gas pressure
monitoring, leak detection, low pressure liquid and hydrostaticpressure measurements.
