Insulation Resistance:
- single or dual elements: 1,000 megohms @500 VDC, leads to case.
- dual elements: 100 megohms @ 50 VDC between elements
Time Constant (typical in 3 ft/sec moving water):
- stainless steel sheath and isolated stainless steel sheath:
- single element: 2.0 seconds
- dual element: 3.0 seconds
- insulated epoxy glass sheath: 2.5 seconds
Pressure Rating:
- standard stainless steel sheath: 100 psi (6.9 bar)
- isolated stainless steel sheath: 100 psi (6.9 bar)
- insulated epoxy glass sheath: 30 psi (2.1 bar)
Repeatability: less than ± .06% change in ice point resistance after 10 consecutive cycles between ice point and 250°C.
Long term stability: less than ± .2% ice point resistance shift after 1,000 hours at 250°C.
Self-heating: 10 mW/C in water moving 3 feet/second
