BCR3150 Blowdown Controller
Description The BCR3150 blowdown controller in conjuction with conductivity probes CP10, CP30/CP40 and CP32/CP42 is used as blowdown controller and limit switch, for instance in steam boilers, (pressurised) hotwater installations as well as condensate and feedwater tanks. A Pt100 temperature sensor may be connected to the controller to provide temperature compensation. This is recommended if the boiler is working at varying pressures, or for other applications such as condensate monitoring or coil boilers, where the temperature may vary. The blowdown controller indicates when the preset MAX TDS/Conductivity is reached and opens or closes a blowdown valve. The controller can provide a MAX alarm. The blowdown controller BCR3150 features the following properties: - TDS/Conductivity control and limit switch using conductivity probes CP10 or CP30/CP40, with or without a separate temperature sensor Pt 100 (TP20) to provide temperature compensation (0 - 250 °C) - TDS/Conductivity control and limit switch using conductivity probe CP32/CP42, with an integrated temperature sensor (temperature compensation) - Manual electronic probe cleaning, to remove scale from probe tip - ON/OFF control of blowdown valve, optional with purge time for probe in pipeline installations - An optional filter to increase damping effects, to avoid overfrequent valve operation - Conductivity to TDS conversion (unit in μS/cm or ppm) - Standby/burner input (24 Vdc), to reduce boiler water loss, if the boiler is on standby or low demand - Actual value output 4-20 mA - Password protection
