Safe and Reliable
McDaniel, designs and manufactures its gauges to minimize
failure and to
protect personnel and property. The use of laminated safety glass, rather than
plexiglass
or single strength glass, prevents dangerous pressure build-up in the case;
- the 2" glass breaks at 60 psi
- the 2½" glass breaks at 40 psi
- the 4" glass breaks at 15 psi
- the 6" glass breaks at 8 psi
The brittle glass cracks uniformly and the laminate remains
intact. Additionally, the
laminated safety glass won't craze or discolor.
Every 4" or 6" McDaniel gauge is designed to
withstand:
- 300% full scale pressure without rupture of the bourdon tube
- 130% full scale pressure without loss of accuracy
- 15,000 cycles of pressure pulsation from 10% to 90% full scale
at a rate of 60 times a minute. The gauge is allowed to rest for 5 minutes and
then can have no greater error than 1% at any place on the dial.
