LMP 308i Detachable Stainless Steel Probe Precision Stainless Steel Sensor accuracy according to IEC 60770: 0.1 % FSO The detachable precision stainless steel probe LMP 308i is designed for continuous level measurement in water and low-viscosity fluids. The signal processing of sensor signal is done by digital electronics with 16-bit analogue digital converter. Consequently, it is possible to conduct an active compensation of sensor intrinsic deviations from normal conditions like nonlinearity and thermal error. Nominal pressure from 0 ... 4 mH2O up to 0 ... 200 mH2O Output signals 2-wire: 4 ... 20 mA 3-wire: 0 ... 10 V others on request Special characteristics ► cable assembly and sensor head detachable excellent accuracy communication interface thermal error in compensated range -20 ... 70 °C: 0.2 % FSO TC 0.02 % FSO / 10K In order to facilitate stock-keeping and maintenance the sensor head is plugged to the cable assembly with a connector and can be changed easily.
