ENVIROSEAL RTD sensors employ a cold end seal that houses a rubber gland. The seal offers a temperature rating of -50 to 204°C (-58 to 400°F) and also exceeded moisture resistance testing in a humidity chamber per ASTM E644 paragraph 15 standards. Additionally, the new RTDs feature a unique design that increases wire pull out resistance by 70% (15 lbf minimum) over existing epoxy designs. Both the cold end seal and the new sensor design, which improves pull out resistance, are patent pending.

The ENVIROSEAL RTD's cold end seal provides extreme protection from salt water, motor oil and chemicals such as bleach, ammonia and boric and nitrous acid. Combined with the sensor's wide temperature rating, the ENVIROSEAL RTD is perfect for a wide variety of applications, including refrigeration or condensation units, food processing, industrial ovens, medical research, packaging equipment and environmental control systems.

The new sensors also feature a vibration resistant design, meet IEC60751, BS 1904 and EN60751 standards and are available with a variety of fitting and termination options.
