Bourdon tube pressure gauges

Adjustable overpressure protectors are used to protect pressure gauges against the effects of pressure exceeding their maximum rating. The BDT49 is spring loaded piston system. Under normal conditions the valve is opened, but when the maximum pressure is exceeded the piston in the valve closes. The valve will remain closed until the system pressure drops approximately 30% below the closing pressure, where upon the force of the spring will open the valve

The ECx is a complete welded construction and designed for those applications where the process conditions are such that direct mounting of the instrument cannot be done. Applications are aggressive media, waste water treatment, or when special wetted parts materials for pressure gauges are required. ECx is typically used in combination with pressure gauges

The BF construction has a seal body that is made of a (forged) blind flange. The weld of the diaphragm to the seal body is a wetted part and therefore diaphragm materials are mostly chosen the same as the flange material. The BF is typically used in combination with (differential) pressure transmitters for applications such as level, flow  and (absolute) pressure measurement.

The BDT40 is a mounting bracket designed to mount pressure gauges to the wall or on a 2” pipe. Together with the BDT41 adaptor nipple the set can be mounted in the location that is required. The design is a clamp that can be opened fully for easy mounting after the tubing or diaphragm seal is mounted. The wall mounting design is based on the DIN 16281.

The BDT45 is an adjustable pulsation protection accessory against sudden pressure pulsations and surges. It is adjustable by means of a throttle screw. The screw closes or opens the open flow in the device so that the fluctuations are dampened. Adjustment of the setting is possible during operation. This enables sensing instruments to provide consistent readings, while extending product service life. The pulsation dampener is often supplied assembled to the pressure gauge. It is not to be used in combination with diaphragm seal.

Swivel gauge adapters are used for easy positioning of a pressure gauge. With the BDT47 swivel gauge design it is possible to adjust the dial face 360° in order to get the best position of readability of the pressure gauge. The swivel gauge prevents difficulties with mounting and positioning NPT thread without the risk of over or under tightening which can cause leakages. This design uses a metal to metal closing system which removes the sealing ring from the assembly. Al wetted parts are made out of the alloy selected.

The BDTM924 Block and bleed model made from square bar stock material. This model is usually seen directly mounted to a pressure instrument nd can be used for isolation, bleeding, calibration and testing of the pressure instrument.

Syphons are used to protect pressure gauges to the effect of hot process media under pressure such as steam. The syphon allows the media to condensate in the syphon. This prevents hot media to enter the pressure gauge. This increases the life time of a pressure gauge with hot media. There are several designs for different installation situation. The BDT42 coil syphon is used for vertical installation, the BDT43 for horizontal installation. The BDT44 is a more compact design of the BDT42 coiled syphon.
