LPI45B00 74CC OVAL 4-20mA IP67 Valve Position Indicator

Description

OVAL LPI45B00 74CC is a precision linkage position indicator featuring a 4-20 mA DC output, 24 VDC nominal supply voltage, and a 10 to 100 mm linear stroke range. The device is constructed with a die-cast aluminum alloy housing finished in melamine resin, providing an IP 67 ingress protection rating and Ex d IIB T4 explosion-proof certification. It operates via a 2-wire electrical configuration, converting mechanical displacement into a standardized current signal through a high-linearity internal potentiometer and transducer circuit. The mechanical interface consists of a robust linkage arm assembly designed for direct coupling to reciprocating or rotary shafts.
