报警系统温度和压力传感器

Finished plan for the engine-room monitoring sensors: Pt100 thermo-resistance bulbs with measuring point list, 4–20 mA pressure transmitters with test pieces and gauge valves, Danfoss KPS thermostats and RT pressure switches. It includes specifications, maintenance and inspection intervals for the bulbs, zero and span adjustment of the transmitters, and setting of the thermostats (range and differential).

保养规程

Pressure transmitter zero and span

1. Power the transmitter for 20 minutes. 第 35 页
2. Disconnect it from the pipe so it sees no pressure; output should be 4 mA ±1 % F.S.; if not, remove the blind screw and adjust ZERO. 第 35 页
3. Reconnect, apply maximum range pressure, output should be 20 mA; adjust SPAN if needed. 第 35 页
4. Repeat zero and span until both are correct. 第 35 页

Setting a KPS thermostat

1. Loosen the locking screw between the spindles. 第 38 页
2. Set the upper (function) temperature on the range spindle and the differential on the differential spindle, e.g. 95 °C with 5 °C differential for a cooling water alarm. 第 38 页
3. Retighten the locking screw; fit the sensor in its pocket with heat-conductive compound. 第 38 页
