- Limitations Which Apply Are
- These units must be operated within the catalogued environmental and application parameters. Determination of failure will be made by NOSHOK, Inc.'s equipment and personnel or a certified test facility specializing in this type of evaluation. Gauge failures determined to be caused by over-range, incompatibility with environment or product media and abuse will not be considered under this warranty. NOSHOK, Inc. will, at its discretion, repair or replace the working parts of the damaged gauge without cost to the customer.
In keeping with and for purposes of product and/or manufacturing process improvements, NOSHOK, Inc. reserves the right to make design changes without prior notice. - Maximum Pressure Limits for Glass Transition Temperature (Tg), Tetoron Cotton (TC) Bottom Housing Material_psi

- Stainless Steel capillaries available with or without Stainless Steel armor
- Protects the instrument from high or low process temperatures
- Allows remote mounting of pressure instrument(s)
- Select the shortest capillary length possible, as changes in ambient temperature conditions may significantly affect the accuracy and response time of the instrument
- Standard length 5', others available
- Installation on analog gauges requires a gauge support and gauge adaptor, or other surface mounting provisions
- Any level difference between the instrument and the seal will result in a pressure indication error; make sure to compensate for the level difference during calibration of the diaphragm seal assembly if the level difference is known
- Filling options for capillaries
- Silicone - specify to 10 or 20 feet (SL-C)
- Halocarbon® - specify to 10 or 20 feet (HL-C)
