Product
Specifications
In addition to the models specified, MSI can make
custom High Temperature VR sensors in other
lengths, diameters, configurations, mounting threads
(e.g., metric) as well as with different operating
specifications and options like pigtail leads, NPT
threads for explosion proof applications, etc. to
satisfy special requirements. If you do not see a sensor
that meets your needs, please contact us and we would be
happy to make a product that meets your
specifications.
Standard Features and
Specifications
- Variable Reluctance (VR) or inductive type (no
internal magnet).

- Three (3) foot stainless steel overbraided lead
- 300 stainless steel housing (locknut included)
- Magnet that resists demagnetization
- Unique potting that compensates for temperature
extremes
- Focusing tip (pole piece) which allows greater air
gap with no signal loss
- Operating temperature range: -450°F to +850°F & +1000°F intermittently
- IR leakage: 50 Mohms @ 50 VDC minimum
- High signal output
- High Shock and Vibration resistance - Impact: 15
G's (11 mS, 1/2 sine) min.; Vibration: 20 G's at 2,000
Hz min
- Unconditional six (6) month warranty if used
within specifications
