The BS2000 is a fully automatic dual compressor bubbler system with bubbler tube purge, tank moisture dump, system status indication, and system fault alarms. The unit provides a 4-20mA analog output representing level for use by other devices to perform pump control or telemetry functions. Tested to UL 61010C-1, the Standard for Process Control Equipment.
(14) The Level Probes provides a rugged, safe, reliable and cost-effective means to measure liquid level for water and waste water pumping applications. The Level Probe may be ordered with one, three or ten electrodes with various spacings and two cable lengths. Intrinsically Safe for use in Class 1, Groups A, B, C, D. Class II, Groups E, F, G. Class III, Hazardous Locations when installed with Intrinsically Safe Barrier, MPE Model ISB10, in accordance with the MPE Drawing 0303.
The Level Probe Relay senses liquid level and provides a relay output for controlling a pump or level alarm. The unit has two inputs, an ON and an OFF, for connection to two electrodes of a conductance probe. All setup is easily done using the DIP switches on the unit.
When used for a level alarm the ON and OFF inputs may be connected to the same electrode on the probe, or the ON input may be used by itself. When used for pump control the ON and OFF inputs are typically connected to two different level probe electrodes to provide a latching function.
The unit has two pump control modes, Pump Down (empty a tank) and Pump Up (fill a tank) (see table below). When in the Pump Down mode and both inputs detect liquid, the unit ...
The Level Probe Converter senses liquid level and provides a 4-20mA analog output for use by a pump controller or PLC to control liquid level. The unit monitors the ten electrodes on a Level Probe, and provides an analog signal that is proportional to level. All setup is easily done using the four DIP switches on the unit. The Sensitivity of the unit must be set for the type of liquid being detected (see table below). The Analog Output Delay setting provides control over how fast the analog output transitions from one level output value to another. It takes 10 times the Analog Output Delay setting value to go from 4mA to 20mA, when the electrodes are covered quickly. When the electrodes are slowly covered one at a time, the Analog Output ...
