A PAIR of 0-21 bar (0-300 psi) pressure gauges, fitted with 2.8mm diameter x 41mm long Binder-style insertion probes.
The pressure gauge has a 304 stainless steel case; a polycarbonate window; a 63mm dual-scale dial; and a full-size Bourdon tube with brass/bronze wetted parts. It is manufactured to BS EN 837-1:1998 and has an accuracy of +/- 1.6% full scale deflection.
The insertion probe has a brass body and a stainless steel needle. The knurled ring has a 3/8″ UNF female thread.
P.T.F.E. thread-sealant is applied to the joint between the gauge and the probe, thus creating a solid seal.
Offered as a useful toolkit addition for circumstances when system parameters might exceed the capabilities of the Comdronic meter being used:
- Use a single gauge to estimate total system pressure [AC6-SP = max. 10 bar / AC6-HP & AC7-HP = max. 20 bar].
- Use a pair of gauges to estimate differential pressure across devices that might give very high readings such as pumps, chillers, strainers, etc. [AC6-SP = max. 200 kPa (2 bar) / AC6-HP = max. 600 kPa (6 bar) / AC7-HP = max. 800 kPa (8 bar)].
In order to help prevent any spikes in pressure from damaging the gauge, it is recommended that the nominal maximum working pressure should be no more than 15.0 bar.
