- Page 9 Installtion of a semi-bridge converters (on Dräger RailGard-W1 and -W4 only) The catalytic sensor in the Polytron SE Ex forms one half of a Wheatstone bridge while the converter board has to provide the second half of this bridge. Therefore it is necesarry to use a semi-bridge converter (Part No. SC00016), if one or more Polytron SE Ex sensing heads are connected to a Dräger RailGard-W1 or - Thus the converter powers the sensor and converts the semi-bridge signal into a 4 to 20 mA signal, suitable for internal processing within the Dräger RailGard.

Page 13: Adjustment Of The Semi-Brdge Converter For Se Ex Sensing Heads
Adjustment of the semi-bridge converter for SE Ex sensing heads The converter must be fitted into a powered Dräger RailGard-Wx for the adjustment procedure. A Polytron SE Ex sensing head has to be connected with the converter. 1. Adjusting the supply voltage for the semi-bridge •... - Page 14 2. Adjusting the zero point • Apply zero gas (e.g. 99.99 % by Vol. N ) to the sensor, which corresponds to ZERO (4 mA). • The output current can be checked with a voltmeter at the two test points on the left hand side of the converter (“Measuring Point 4-20mA”).
