WTYKB Mining Explosion-Proof Temperature Controller
The WTYKB series mining explosion-proof temperature controller uses a temperature-sensing capsule with a spring tube for pressure sensing. It is designed for automatic temperature control in I-class areas and has an explosion-proof rating of Exdb Ⅰ Mb. The controller features a temperature-sensing liquid and a C-type spring tube to detect pressure changes, triggering a microswitch to control temperature. It is suitable for use in environments requiring corrosion protection with a stainless steel sheath and has a temperature setting range of 10°C to 120°C.
