Turbo pump oils:
| Vendor | Model | Viscosity | Density | Vapor Pressure | Notes |
|---|---|---|---|---|---|
| Apiezon | AP303 | 29 mm²/s @ 40 °C | 0.97 g/mL @ 20 °C | 3.1E-7 Torr @ 80°C | |
| braycote | 815Z | 148 mm²/s @ 38°C
45 mm²/s @ 100°C |
4E-13 Torr @ 20C
2E-9 Torr @ 100C |
DO NOT USE THIS. Only in here for reference
Viscosity is way too high
| |
| Cambridge Mills | CMP500 | 8.7 mm2/s @ 130C | 0.922 g/mL @ 22C | 0.1 mm @ 130C | "Hydrocarbon Oil"
A&J: "TL011 is discontinued and Pfeiffer does not offer a replacement for it. You could use CMP500, which is chemically identical." |
| Dymavac | 500 | 8.7 mm²/s @ 54 ° C | 1E-7 Torr @ 25°C | ||
| Leybold | HE500 | LVO variant required?
98-198-053 98-198-030 | |||
| Leybold | Leybonol | 13 mm²/s @ 40 °C
3.5 mm²/s @ 100 °C |
925 kg/m3 @ 15C | "<0.5 Pa @ 20C" | Replaces HE500
Oil type: Synthetic oil (Ester oil with additives) "Bearing lubricant for turboradial blowers." TURBOSTREAM |
| Pfeiffer | TL 011 | 10.5 mm²/s @ 40 °C | 0.947 kg/dm3 @ 20 °C | No data | TPU/TPH official oil |
Notes:
- 1 centistokes =1 millimeter²/second
- 1 cSt = 1 mm2/s
Sensor
McMaster sensor state 2024-07-17
- Got burned by mismatched GP275 sensor to gauge
- I thought it was going to give an error like 40%, but its actually a zero point error => massive misreading / order of magnitudes
- Inficon
- Found 3x BCG450 at flea market. 1 / 3 work
- Notes
- MKS 901P might also go into ecosystem
GP275
GP275 controllers:
- GP375
- Green display
- RS232 as DB9
- Circa 2009
- 275106, 275108
- Red display
- Cable seems to be uncommon
- Cable has AC + GP275 connection
- Granville-Phillips 316 Vacuum Gauge Controller 316001
- IG controller
- Integrated power supply, controller
- HP 59827A
- Rebranded GP
- Somewhat similar to Granville-Phillips 316 Vacuum Gauge Controller 316001
- Half width IG controller (integrated PS / controller)
- Rebranded GP
- Granville Phillips 307001
- Full width IG controller (half PS, half controller)
- RS232 is optional card
GP275 sensor
Can get ones with integrated controllers. You can take the sensor out of them but it doesn't have the keying on the connector
Haven't played with DeviceNet, RS485, etc direct control on these
MKS 901P
Hastings HPM-2002
Interesting but tubes are relatively scarce on surplus market
Nice integrated display + sensor pluggable architecture

HASTING INSTRUMENTS VACUUM GAUGE MODEL 760 110-220 VAC 760
TELEDYNE HASTINGS DUAL SENSOR VACUUM GAUGE MODEL HPM-2002-OBE
HVG-2020B
Teledyne Hastings HPM-2002 Digital Dual Vacuum Digital Gauge w/ RS232 Option
