RTAS & RTAS-EP Ambient Sensing
|
RTAS is an ambient-sensing thermostat which is generally used for freeze protection in ordinary (non-hazardous) areas. The thermostat is mounted through the end of the oblique sided enclosure lid. In fact, because there is so much room in this model, multiple heating cables can be terminated. The stainless steel sheathed, inverted bellows probe provides good sensitivity, resulting in more accurate control. RTAS-EP is a modified version of the RTAS which utilizes a hermetically sealed switch. Since this switch has no arcing contacts, it can be used in Division 2 Hazardous Areas. |

RTBC & RTBC-EP Bulb & Capillary
| RTBC is a line-sensing thermostat which is generally used for process temperature maintenance applications in ordinary (non- hazardous) areas. The thermostat is mounted within the enclosure and the capillary is brought out through one of the openings in the bottom of the box. This design provides extra protection for the capillary, especially when the control is mounted on a pipe, for heat tracing applica- tions. The three foot long stainless steel capillary provides good flexibility in mounting locations.
RTBC-EP is a modified version of the RTBC which utilizes a hermetically sealed switch. Since this switch has no arcing contacts it can be used in Division 2 Hazardous Areas. |

RTSS Solid State Line Sensing (RTD) Control
| RTSS is a line-sensing solid state controller which is used for process temperature maintenance applications where more precise temperature control is required. This control is supplied with a specially designed RTD sensor. The sensor has a stainless steel sheath and waterproof insulated TFE lead wires. The controller provides excellent accuracy and high current switching ability in a small enclosure. |  |
Thermostat Specifications
| Temperature Setpoint Range RTSS-A = 0 – 100F (-18 – 38C) RTSS-B = 50 – 250F (10 – 121C) RTSS-C = 200 – 600F (93 – 316C) |
