Product Description

The LEO 3 loop powered pressure gauge is externally protected to IP65 and a Binder 723 5 pin connector on the back of the case provides connection for the series loop or digital interface.  The plastic case can be further protected from impact via an optional rubber protection boot cover.  

Using the optional PC software the 4-20mA analogue ouptut can be altered to a different scaling.  Pressure readings can also be transmitted directly to a computer and recorded without the need to connect the 4-20mA current loop circuit.
