Posifa PVC6100 MEMS Pirani Vacuum Gauge
Atmosphere-to-medium-vacuum gauge with manufacturer-stated nominal measurement range 10⁻⁴ Torr to atmosphere. Provides 0–10 V analogue signal through FCC-68/RJ45 connector; configurable output curve for some gauge replacement requirements. Industrial applications include freeze drying, mass spectrometry and vacuum furnaces.

Manufacturer model codes, connector, fluid compatibility and individual operating parameters must be confirmed from the current datasheet; a model family description is not an order-specific industrial safety approval.
PVC6100 — analog RJ45 gauge, replaceable factory-characterized probe
| Attribute | Original Posifa data | System consequence |
|---|---|---|
| Measurement method | Second-generation MEMS Pirani thermopile sensing element with a low-temperature microheater | Sensitive from 10⁻⁴ Torr to ATM according to published product description. |
| Connection and analogue output | 0–10 V signal through FCC-68/RJ45 connector | Not the I²C bare PCB output of PVC4100; correct wiring and controller voltage scale needed. |
| Field replacement strategy | OEM offers output mapping to emulate other manufacturers’ vacuum gauge curves | Plug-and-play replacement only after connector, mechanical fitting and voltage transfer curve are matched. |
| Contamination resistance | Low heater temperature and sealed microfabricated thermal chamber mitigate filament contamination | Process gas contamination and pressure pulses still need assessment. |
| Use cases | Freeze dryers, mass spectrometers, cryogenic tanks, distillation, vacuum furnaces and load-locks | Validate overpressure, seal, venting and sensor recovery for each process. |
Pressure-range, media and product photo controls
A Pirani gauge’s reading is gas-conductivity dependent. The 10⁻⁴ Torr to ATM envelope is not a universal uncertainty specification. PVC6100 and PVC6800 may share replacement applications but different pressure ranges and composite sensing electronics.
