FIELD: instrumentation engineering. SUBSTANCE: given pressure relay is intended for use in test and control systems mounted predominantly on mobile objects exposed to intensive impact actions. Pressure relay incorporates case 1 housing two aneroid boxed formed by membranes 2 and 3, 4 and 5 acting as sensitive elements. Mobile contacts 7 and 8 are positioned on membranes 3 and 4 facing each other. Two-side immobile contact 10 which contact surfaces face mobile contacts 7 and 8 is anchored in strap 9 of case 1 between mobile contacts 7 and 8 uniaxially to them. Mobile contacts 7 and 8 are electrically coupled to output terminals 11 and 12 through membranes 3 and 4. Testing mobile contacts 14 and testing immobile contacts 15 are installed in case 1 on side of membranes 2 and 5 facing outwards. EFFECT: increased functional reliability of pressure relay. 2 cl, 2 dwg |
