A new Simple R1-M.B77 adjustable level control switch for the monitoring of liquids for both industrial and civil, has been launched by Val.Co. Jan Grobler, MD of GHM Messtechnik South Africa comments, “This product offers the customer a unique feature inasmuch that the rod, which comes in lengths of either 1 metre or 500 mm, can be shortened to the length to suit the purpose. This level switch is brand new to the South African market, extremely competitively priced and suitable for a variety of level applications”.

The operational principle is based on the drive of a micro-switch which is located in the head of the instrument as a result of the hydrostatic thrust which is exerted by the liquid on the float. The absence of moving parts offers extreme ruggedness and reduces the need for maintenance.

Technical specifications

With an adjustable switching point and closed cell float, the instrument also offers a 3A Single Pole Double Throw (SPDT) micro-switch as well as a Single Pole Single Throw (STST) option. It has an operating ambient temperature of -30/+55 degrees centigrade with a 90% relative humidity.

Easily mounted, threaded or flanged, it has an NBR (oil resistant rubber) flat sealing gasket while offering a minimum degree of protection of IP65. It comes with a DIN 43650-A plug.

“I see great interest in this recently-launched adjustable level switch, across a wide section of industrial, domestic and agricultural applications where water/liquid level monitoring is crucial. The customer is going to benefit immensely from its innovative design. Additionally, it is available in nylon and fibreglass (Model R1-M) or stainless steel/brass (Model R1) version,” Jan concludes.
