• On resistance to climatic influences devices have execution of U3, and also execution of T3 in accordance with GOST 15150 - 69 (but for work at a temperature from — 50 to + 60 °C)
• Devices maintain impact of vibration in the range of frequencies from 5 to 35 Hz with an amplitude of 0,35 mm (L1 group in accordance with GOST 12997 - 84)
• Devices are manufactured with a carving of the connecting M20 * 1,5 - 8g union, G1/2 - B, R1/2
Parameters of the signaling device for the signaling manometers
• The signaling device on connection of external chains has four options of execution in accordance with GOST 2405 - 88:
o III — two disconnecting contacts: the left index (min) — blue, right (max) — red.
o IV — two closing contacts: the left index (min) — red, right (max) — blue.
o V — the left contact disconnecting (min), right closing (max) — both indexes blue.
o VI — the left contact closing (min), right disconnecting (max) — both indexes red. Note: By request of the consumer the signaling device can be produced with magnetic preload of contacts for any of above the specified executions.
• Tension of the external switched chains:
o of 380 V (including 24; 27; 36; 40; 110; 220B) — for chains of alternating current;
o of 220 V (including 24; 27; 36; 40; 110B) — for chains of a direct current
• Explosive power of contacts for the signaling device:
o with the sliding contacts — 10 W of a direct current and 20 V • And alternating current;
o with magnetic preload of contacts — 30 W of a direct current and 50 V • And alternating current
• Value of the switched current:
o for the signaling device with the sliding contacts — from 0,02 to 0,5 And;
o for the signaling device with magnetic preload of contacts — from 0,01 to 1 And
• A limit of the allowed key industry of operation of the signaling device:
o for the signaling device with the sliding contacts of 2,5%
o for the signaling device with magnetic preload of contacts of 4%
