FIELD: measurement technology. SUBSTANCE: bellows pressure gauge has bellows 1, union 2, ohmmeter 3 and flexible resilient cord made in form of loop of resilient thread 4. Thread is made of current-carrying rubber and is placed in insulating sheath 5 made of resilient flexible material (rubber or latex). Bent part of thread loop 6 is rigidly connected with movable cover 7 without electric contact of thread 4 with bellows and cover 7. Other part of loop is connected to bellows fixed base 8. Free ends 9 and 10 of thread 4 are passed through base 8 by means of sealing insulators. Sheath 5 plays part of sealing insulators of free ends 9 and 10 which are connected to inputs of ohmmeter 3. Insulating gasket 11 made of flexible resilient material is placed between loop threads. Cord is connected to cover 7 and base 8 by means of washers 12 and 13. EFFECT: enhanced reliability of operation. 1 dwg
