Differential pressure gauge ДСП-160-М1
Differential pressure gauge ДСП-160-М1 differential bellows indicating are designed to measure the flow rate of liquid, gas or steam by the pressure drop in the restricting devices, the vacuum or overpressure drop. For measuring the differential pressure on gas meters, gas filters, and other gas equipment. Differential pressure gauge according to TU 25-7310.0063-87 is produced. Industries: gas supply, heat and power engineering, chemical industry. Medium: natural gas, nitrogen, argon, air, and other non-aggressive gases. Differential pressure gauge ДСП-160-М1 technical characteristics: Ambient temperature: from - 40 to + 70 ° С; Relative humidity 80% at an ambient temperature of +35 ° C. The standard version includes ammonia (A) and oxygen (K) versions. By the type of measurements, they are distinguished: differential pressure gauges, flow meters, differential pressure gauges, differential pressure gauges, differential pressure gauge DSP-160-M1 & mdash; showing without additional devices Maximum permissible operating overpressure, 63; 160; 250; 320 kgf / cm2 Limit nominal pressure drops, 0.063; 0.1; 0.16; 0.25; 0.4; 0.63; 1; 1.6; 2.5 kgf / cm2 & ndash; for overpressure up to 63 and 160 kgf / cm2, and 0.4; 0.63; 1.6; 2.5; 4; 6.3 kgf / cm2 & ndash; for overpressure up to 250 and 320 kgf / cm2 Accuracy classes: 1, 1.5 Upper limits of measurement of differential pressure gauges-flowmeters A & mdash; are selected from the row and one of the numbers in the row: 1; 1.25; 1.6; 2; 2.5; 3.2; 4; five; 6.3; 8, where A = a * 10 n, where n & ndash; an integer (positive or negative) number or zero. The upper measurement limits of differential pressure gauges must correspond to the limiting nominal pressure drops. Principle of operation: Structurally, the differential pressure gauge consists of two parts - a bellows block and an indicating part. The principle of operation of the DSP-160-M1 differential pressure gauge is based on the use of deformation of an elastic system (bellows, cylindrical springs, torsion tube) under the influence of a measured pressure drop on it. The mechanism of the showing part is assembled in a round case with a diameter of 160 mm and is a tribo-sector mechanism with an indicating arrow on the axis of which. The differential pressure gauge scale is uniform with the price of one division 1mbar (10 mm of water column). Overall dimensions, mm: 195х153х136 Connecting thread М22х1,5-8g Weight, no more than 16 kg
