Thông tin sản phẩm:
Diaphragm pressure switches are pieces of equipment with safety functions as set down in the Pressure Equipment Directive (PED). They are suitable for protecting the pressure device should the pressure rise above, or drop below, the approved boundary limits. They come under the remit of PED 1G Category IV and have been subjected to an EC type-examination. The requirements of DIN EN 1854 are met. These pressure measuring devices may only be operated with the electrical evaluation units set out below, and within the area of application of this certificate. The pressure switch is composed of the pressure measuring device and electrical evaluation unit.

Pressure switches with bourdon tubes are pieces of equipment with safety functions as set down in the Pressure Equipment Directive (PED). They are suitable for protecting the pressure device should the pressure rise above, or drop below, the approved boundary limits. They come under the remit of PED 1G Category IV and have been subjected to an EC type-examination. The requirements of Approval Certificate Pressure 100 from the German Technical Inspection Authority (VdTÜV) are met. These pressure measuring devices may only be operated with the electrical evaluation units set out below, and within the area of application of this certificate and the VdTÜV component identification number. The pressure switch is composed of the pressure measuring device and electrical evaluation unit.
Because of its robust design, it is suitable for use in tough environments.
The pressure switches are suited for connection to Zone 0, when fitted by manufacturer with Zone 0 adapter.

Thông tin sản phẩm:
The pressure gauge type series BR42.. has been especially constructed for the operation with diaphragm seals. A custom bourdon tube that is reduced in volume produces a very slight temperature error. Diaphragm seals with reduced membrane surface areas may also be used. A large selection of diaphragm seals − D5 product category − is available for a variety of applications.
