The members of the floater-magnetic level switch, remote level indicator and level gauge family, manufactured by OMUV, can be applied for liquid level sensing, switching, remote indication and measurement in oil and gas industry, water management, pharmaceutical, food and chemical industry, in explosive environment from -60°C.
The instruments are primarily made with Ex (pressure-proof) housing which is certified by EXA ATEX.
The OMUV 05 can be mounted with flanges (or threaded) onto the top of the tank. As the liqud level changes, the magnetic floater moves along the steel (WNr. 1.4301) probe tube welded into the flange. The sensors built into the probe tube provide receivable signals, generated by the magnetic field, on the wiring terminals in the aluminum switching case. These can be switching signals or signals proportional with the level in the tank.
In different instrument types, the indication task is determined by the sensors:
- level switch:
its sensors are magnetic switches, reed relais
. Operation: bistable reed switching on to rising level, monostable, monostable with limiter ring
- level transmitter:
probe built from reed relais and resistors
with 4..20 or resistance output signal
- remote level indicator with display: probe built from reed relais and resistors
with 4..20 or resistance output signal, with local display
- level meter:
its sensor is a magnetostrictive wire
with 4..20mA signal, 1mm accuracy
