These test pressure gauges are manufactured to the very highest standards and are used to test pressures of tanks, pipes fittings and in laboratories.
Measuring principle
The precision test pressure gauges habe a high-grade measuring element. The pressure proprtional elastic deformation of the Bordon tube is transmitted through a low friction movement to the knife edge pointer.
With the help of the scale on the dial you can read the current pressure at measuring element.
Installation
The gauges are most often installed straight into the customer’s screw necks. The fine pressure gauge in carrying case is assembled using the accessories supplied (valve etc.).
Connection
The gauges are supplied with a G½ connecting thread as standard. The connection is made of brass or stainless steel.
The gauges can be used with non aggressive gaseous or liquid, but not with highly viscous or crystallizing media.
Other´connection types are available on request.
Measuring ranges
The measuring ranges are graduated according to DIN recommendations and lie between 0.6 bar and 2500 bar.
Other scales with measuring ranges in PSI, Pa or with your company logo are available on request.
Damping liquid
Pressure gauges with liquid filling are used in locations with high alternating dynamic loads, strong vibrations and pulses.
The filling ensures easy readability through steady pointer movement even when subjected to extreme loading and heavy vibration. The lubricating effect of the glycerine also keeps wear to a minimum. Glycerine is always used as a matter of principle. In gauges with a contact or an electrical measuring transducer, liquid paraffin is used as a nonconductive alternative.
Silicon fillings of various viscosities are also optionally available. Please note, that not all precision type devices can be filled with liquid.
Contacts
For monitoring the system pressure gauges can be fitted up to 2 limit contacts.
Inductive contacts are also available. (see Chapter Contact Device).
