It is a high-precision and slip resistance level transducer. It converts level mechanical signals from UZG 100 series float steel-strip level indicator into standard current signal output of 4-20 mA via transmission gear, variable speed gear and electric potential sensing system.
Application:
It is used together with UZG 100 series float steel-strip level indicator manufactured by our company. It has been widely used in many industries, such as petroleum, chemical, electric power, metallurgic, environmental protection and food industries. Its measuring values can be transmitted to a remote control room for display or to a control computer for data display, control and alarm.
