Model 85M1S series is a low pressure transmitter, which is developed to measure low pressure down to 0.2 mbar. It features a dedicated design with a 3 ½ LCD display of light blue backlight. The light blue backlight allows 851S series transmitters to be used in dark. The V-shaped pressure inlet is for pneumatic connection through a hose. This inlet can be either in radial direction (as shown) or axial direction. A 1/4 NPT connector is used as electrical interface to ensure IP 67 protection.
The 851S series is found a precision transmitter of high stability for a number of measuring ranges, spanning from 0~0.2 mbar to 0~10 bar. Its output signal is conditioned to 4~20 mA current loop, 0~5 Vdc or 1~5 Vdc with the accuracy up to 0.1 %FS (FS = full scale). Both gauge and differential pressure can be measured with 851S transmitters. For gauge pressure measurement there is one V-shaped inlet (as shown), while for differential pressure measurement there are two inlets fixed on the transmitter’s housing. 
851S series transmitters are ideal devices which can be installed for industrial automation and sanitary applications, and the pressure medium is limited to dry and non-corrosive gases.
