Notes & Disclaimers
Housing Material Compatibility: Above +85C, Trogamid is suitable for water-based liquids. Oil-based liquids may cause deformation and require compatibility testing. Always check fluid compatibility with Polysulfone or Trogamid before use.
Hex Nut and O-ring: Sold separately. Contact technical@sstsensing.com for details.
NPT Version Sealing: Can be sealed with PTFE tape.
Output Circuit Configurations: Identified by a 3-digit code at the end of the part number. Consult the 'ORDER INFORMATION' section for details.
Load Connection Caution: The minimum load impedance should not exceed Vs/max output current. Shorting the output to Vs or 0V will cause irreparable damage.
General Note: SST Sensing Ltd. reserves the right to change product specifications without notice. All information is subject to SST Sensing Ltd.'s data and considered accurate at the time of printing.
Customer Application Responsibility: SST Sensing Ltd. provides information without legal responsibility. Customers must test under their own conditions to ensure suitability for their intended application.
Cleaning Agents: SST Sensing Ltd. recommends alcohol-based cleaning agents. Do NOT use chlorinated solvents (e.g., trichloroethane) as they can attack the sensor material.
Maximum Ratings: Do not exceed maximum ratings. Ensure sensors are operated according to requirements. Follow all wiring instructions carefully to prevent permanent damage.
