GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM STRAP-ON LOW LIMIT THERMOSTAT TLSO SERIES PRODUCT DESCRIPTION The single point strap-on low limit thermostat incorporates a precision thermistor temperature sensor and provides a Form C relay output (NO/ NC) with an adjustable setpoint. The sensor is encapsulated in a 38.1 mm x 12.7 mm (1.5” x 0.5”) machined aluminum heat sink. A 254 mm (10”) S/S Pipe clamp is provided to secure the assembly to various sizes of pipe. All probes are constructed to provide excellent heat transfer, fast response and are potted to resist moisture penetration. A hinged and gasketed Polycarbonate enclosure is included for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The strap-on temperature transmitter series can be mounted directly to various sizes of pipes and secured using a 254 mm (10”) S/S pipe clamp. If necessary, remove a section of insulation from the pipe. The 254 mm (10”) S/S pipe clamp is a “Quick Release” type and can be separated by moving the tightening screw so that it is perpendicular to the clamp and slide the clamp apart. Position the aluminum plate on the pipe so it makes the best contact, wrap the clamp around the pipe and re-assemble and tighten. Any excess clamp may be cut off. For best results, thermal conductive compound should be applied to pipe prior to mounting the probe. Wiring connections are made inside the enclosure.
