LEVEL SWITCHES type ERH--06

LEVEL SWITCHES IN MARINE VERSION ARE DESIGNED FOR SIGNALLING OF LIQUID LIMIT LEVELS OR TWO-TERM LIQUID LEVEL CONTROL IN OPEN AND CLOSED PRESSURIZED TANKS, IN NON-EXPLOSIVE ATMOSPHERE. THE CONTROLLERS CAN OPERATE ON SHIPS IN MARINE CLIMATE. THE LEVEL SWITCHES ARE PROVIDED WITH CERTIFICATES ISSUED BY: GERMANISCHER LLOYD, LLOYD'S REGISTER, DNV, ABS, PRS, PZH. LEVEL SWITCHES CAN OPERATED IN AGGRESSIVE LIQUIDS NOT REACTING ON 1H18N9T STEEL.
