• Stewart Automotive Equipment has introduced the Bedia range of capacitance fluid level monitoring switches designed for monitoring the levels of oil, water and fuel in diesel and petrol vehicles — but now finding new markets. The switches are compact, mounted in metal housing and, fully self contained, require no remote electronics.
The principal advantage of these capacitance switches over conventional float switches, says the company, is their high mechanical strength and resistance to high-frequency vibrations, for having no moving parts, they cannot be affected by dirt.
When the electrics are switched on, current passes through the probe, providing a signal to a lamp or relay, proving that the wiring circuitry is correct and that the probe is working. There is a time delay of seven seconds before the signal, to allow for the swell of the fluid when the switches are fitted to moving vehicles and mobile plant.
There are over 40 different models to choose from for use in oil, fuel or aqueous liquids. There are switches to monitor maximum and minimum levels through the voltage range 9 to 32v dc and a power supply unit is also available for converting 240v ac down to 24v dc.
