Description

Ultrasonic liquid level switch with rod sensing element. It is used to control the level of liquid at a predetermined level. This device is produced in modifications with one and two points of control. It allows to determine two liquid levels with one instrument.
Operation of SZHU-1 is possible both in the simplest environments (water at room temperature and atmospheric pressure) and in explosive areas with overpressure at extreme temperatures.
Due to the presence of river and marine certificates for these signalling devices, they are actively used on ships of various purposes. It is also necessary to emphasise the fact that the device has no moving parts, which prevents false alarms when the vessel rolls.
There is a wide range of choice of output signals, namely: "current loop", "dry contact", NAMUR or other option on request.
The sensing element of the signalling device is made of stainless steel 12X18H10T.
