The Rhomberg PBX pressure gauge is ideal for applications were high accuracy and durability is required and where the risk of Bourdon tube failure could compromise the safety of the operator.
All gauges are retro-fillable and totally repairable. A number of optional accessories are available either as factory fitted or retro-fitted. A Rhomberg vibration free movement [VFM] can be fitted where filling material is not allowed or excessive vibration is present.
The 54mm dial size safety pattern design is especially suitable for welding and medical gas regulators. Solid front baffle and flimsy back blow-out for all bottom entry gauges to meet SABS and U.L safety requirements as standard.
PBX Pressure Gauge Configuration
| Bezel | P.B.T Polybutyleneterephthalate - colour coded | |
| Back Plate |
Fitting:
non-screw fitting, locating by interface fit when used in conjunction with the diaphragm
Back Vented:
to permit gauge "breathing"
|
|
| Case & Bezel | P.B.T Polybutyleneterephthalate - colour coded. Fully open back for the maximum area to release pressure in case of a major failure. | |
| Dampening Fluid | Glycerine [54mm cannot be filled] | |
| Dual Purpose Dibphragm |
Material:
natural rubber
Operation:
the diaphragm acts as a backplate seal and is stretched over the full diameter of the backplate, allowing for the expansion of air or the filling medium in the gauge.

| Adjustments |
Either by removing the bezel and window and using a micro-adjust pointer or by removing the backplate and diaphragm and adjusting the movement.
|
|
| Pointer | Black aluminium, micrometer adjustable | |
| Connections | 1/8" + 1/4" [BSP - NPT - BSPT] | |
| Maximum Range | 60 MPa | |
| Accuracy | 1.0%FSD [optional 0.5% FSD] | |
| Approvals |
Explosion Tests:
In line with U.L 404 which requires a controlled volume explosion bursting the Bourdon tube with the backplate dislodging in preference to the window.
IP65 Tests: approved,
SABS 1062: approved
