Liquid flow switch RPZH-1M Non-contact liquid flow switch - for continuous monitoring of the presence of liquid flow. When the liquid supply is interrupted or the flow rate drops below the set value, a discrete signal appears (relay contacts closure) at the output from the device. Liquid flow switch RPZH-1M is intended for switching electrical circuits when the liquid (water) flow rate has reached the set value. It is used to control the flow of water in cooling systems of various equipment with an open drain, for example, electrothermal equipment in the metallurgical, oil refining, energy, and chemical industries. RPZh-1M technical characteristics Working environment: water: purity not less than 10 class according to GOST 17216-71, temperature from +5 to + 70 ° С Working environment pressure: from 0.05 to 0.40 MPa (from 0.5 to 4 , 0 kgf / cm2). Limits of setting (setting) flow: - lower no more than 1.5 l / min; - top not less than 30.0 l / min Switched electrical signal: - DC voltage from 0.2 to 30 V; - AC voltage from 0.2 to 250 V; - current, direct and alternating from 2x10-4 to 30 A; - maximum power of RPZh-1M 70 W, 300 VA. Return area: no more than 0.5 l / min. Range of operations: no more than 0.2 l / min. Nominal bore: 15 mm. Weight: no more than 0.22 kg. RPZh-1M operating conditions Temperature from +1 to + 60 ° C, relative humidity up to 98% at a temperature of 35 ° C (version B4 according to GOST 12997-84, which corresponds to version UHL 4 according to GOST 15150-69). Conditions corresponding to the IPX4 marking according to GOST 14254-96.
