IPT122-30-30-PSI-VSF-3
Brooks Instrument 2-Inch Indicating Pressure Transmitter
About this part
Brooks Instrument IPT122-30-30-PSI-VSF-3 is a stainless-steel IPT122 Series indicating pressure transmitter. The documented code structure identifies PSI units, a face-seal swivel female pressure connection, and a 1–5 Vdc ground-referenced output. The recorded 30-30 pressure-range segment is not defined in the manufacturer’s published range table, so the operating span requires confirmation from a physical label or manufacturer order record
Configurations vary. Verify the exact unit before choosing a replacement.

What Does IPT122-30-30-PSI-VSF-3 Mean?
The manufacturer’s ordering structure establishes five fields. Four values decode directly; the recorded pressure-range value is not defined in the published range table.
| Segment | Field | Interpretation |
|---|---|---|
| IPT122 | Base model | IPT122 pressure transmitter |
| 30-30 | Pressure range | Recorded range option; not defined in the published manufacturer range table, so the operating span is not asserted |
| PSI | Units | Pounds per square inch |
| VSF | Pressure connection | Face-seal swivel female |
| 3 | Transmitter type | 1–5 Vdc ground-referenced output |
Documented Application Context
The IPT122 family was designed for high-purity semiconductor gas-delivery systems, including bulk-gas installations, gas cabinets, distribution systems, and gas panels. It provides local dial indication and a remote analog signal suitable for PLC or data-acquisition interfaces.
Calibration and Service Notes
- The IPT122 is factory calibrated for its specified output; field zero and span adjustment is required only when those settings have been changed or a different output is required.
- Pressure-cycle the mechanism before calibration to ensure that the gauge movement returns to its home position.
- Brooks recommends annual pressure cycling to verify smooth operation and the zero and span settings.
- Remove process pressure and disconnect electrical power before service.
- Confirm that all pressure-boundary and sealing materials are compatible with the process fluid and operating conditions.
