TXR and TXL temperature switches provide mechanical temperature control in hazardous industrial locations. The TXR uses a remote bulb and capillary; the TXL senses local ambient temperature. Both standard models have externally adjustable setpoints and SPDT snap-action contacts.

The silicone-filled sensing system and corrosion-resistant enclosure suit demanding process and freeze-protection applications. Select the model for its specific adjustment and media temperature limits. Contact Mod-Tronic to confirm approvals and suitability for your installation.

Selection and ordering

The table lists the two standard SPDT part numbers. A TXR-L2S-10R-Q10 relay version is available by inquiry. Its current catalogue gives conflicting 120 VAC and 240 VAC coil voltages; Mod-Tronic must confirm the required coil before ordering.

Use a suitable thermowell where process pressure or installation conditions require one. Do not exceed the model-specific media limits. Availability is by inquiry.
