YTX-100/150-BT proof electrical contacts mounted disk
The instrumentation system according to national standards:
GB/T1226-2001 "general pressure gauge," the national standard;
GB3836. 1-2000 "Electrical equipmentfor explosive gas atmospheres
Part I: General requirements"; GB3836. 2-2000 "explosive atmosphere
electricity equipment Part 9: flameproof "d" "the relevant
provisions and JB/T9773-1999" electrical contacts, "industry
standard design and manufacturing.
The instrument categories flameproof explosion, the explosion-proof
mark dBT6.
I. Purpose
The instrument used in the environment of an explosive mixture of
dangerous places, used to measure copper and copper alloys, carbon
steel and other non-corrosive non-crystalline, non-freezing medium
pressure (negative pressure).
Through the contact device and the electrical properties with the
corresponding pieces of proof supporting the use of. On measured
media pressure, automatic control, alarm, signal remote and other
features.
Note: Embedded (AXIAL band edge) explosion-proof electrical
contacts: for fixed by installed panel (console) and the wall to
use.
Note: The measurement of corrosive, crystallization and
solidification of the medium requires the use of acid, corrosion or
explosion-proof electric contact diaphragm pressure gauges, for
measuring small pressure (10Kpa ~ 60Kpa), requires the use of
explosion-proof electric contact diaphragm pressure gauge,
measuring a Please use the occasion vibration-assisted magnetic
electric contact pressure gauge or digital explosion-proof electric
contact pressure gauge.

Third, the structure and working principle
1 explosion-proof instrument shell structure, when its explosie
mixture inside the enclosure by sparks or arcing due to the impact
when the explosion occurred, not to cause an explosion outside an
explosive mixture, so as to achieve the goal in explosion-proof.
2, the instrument consists of pressure meter and an electric
connection device composition.
Instrument works: When the measured medium into the spring tube, to
produce the displacement is amplified through the transmission, the
pointer to the measured pressure value indicated on the dial out,
then the pointer device event driven electrical contact, when When
the pressure reaches a predetermined value, activities and set the
needle contact contact contact connected to the circuit.
