Penberthy Low Pressure Flat Glass Gages

For less demanding process conditions. Penberthy’s low pressure gages are designed to maximize the mechanical
and economical advantages of ductile iron covers.

All materials in low pressure gages conform to ASTM specifications. RL gages can achieve pressures to 2400 psig [16550 kPa] @ 100ºF [38ºC] and TL gages can achieve pressures to 2000 psig [13790 kPa] @ 100ºF [38ºC] when manufactured with size 1 glass – see ratings table below.

Penberthy does not recommend low pressure gages for steam/water applications.

Penberthy Medium Pressure Flat Glass Gages

For most common process conditions. Strength and versatility make Penberthy’s medium pressure gages ideal for most common process conditions. Offshore specification 2600.1 is preferred with medium pressure gages in offshore and other corrosive environments.

All materials in medium pressure gages conform to ASTM specifications.
RM gages can achieve pressures to 3000 psig [20680 kPa] @ 100°F [38°C] and TM gages can achieve pressures to
2500 psig [17240 kPa] @ 100°F [38°C] when manufactured with size 1 glass – see ratings table below.

Although not designed for thermal cycling, Penberthy allows use of medium pressure gages for steam/ water applications due to historical precendence - see Application Report 2781 in Penberthy Catalog.
