LPJ-12D/FI photoelectric electric pulse converterDetailed product description：

The LPJ-12D photoelectric pulse converter is a new type of explosion-proof photoelectric converter, which mainly converts the angular displacement of various flow meter output shafts into electrical pulse signals and transmits them to the corresponding receiving instruments. This converter can operate within the voltage range of 12-24V, and the signal is divided into three output channels in square wave form for the display instrument to measure the flow rate of the flowmeter.

The LPJ-12D/FI photoelectric converter not only has the function of LPJ-12D, but also has the function of outputting analog signals of 4-20mA. It can simultaneously output flow pulse signals and standard DC current signals for remote transmission to the receiving instrument.
This product standard number: TDSM11-2005
