WIKA SB15 汽包式温度计 安全温度限定器 表圆60 80 蒸汽发生器

  Applications
   ■ Temperature monitoring for water, oil and gas
   ■ Compressors
   ■ Steam generators
   ■ Temperature control and limiting devices for heatgenerating systems

  Special Features
  ■ High switching safety
  ■ Temperature control and indication in one gauge
  ■ Disconnection in case of capillary-break

 Description
  In case of deficiencies, the safety temperature limiter Model SB15 puts the system into a safe working order. The shifting disc, which is arranged on the pointer shaft, actuates the switching operation at the micro switch when reaching the non-adjustable switch point or in case of capillary break and locks the current status. A reset is possible with a tool only after a temperature decrease by approx. 3 % of the scale range, if there is no capillary-break.
