Obsolete: Field-Adjustable Thermostats & Temperature Controllers
Brand: Parker HannifinMultitube® Field-Adjustable Thermostats and Temperature Controllers are used to monitor the temperature of the process tubes or observe the ambient temperature in chemical processing and refinery applications.
Each thermostat is a mechanically actuated on/off switch that controls the power to an electric tracer to achieve the desired process tube temperature.
The high and low temperatures are pre-set at the factory but are field adjustable and tamper-proof, in order to meet specific application requirements and to avoid unwanted modifications to required settings.
Features- Field-adjustable to accommodate diverse application conditions
- Tamper proof to eliminate unwanted or unauthorized alterations to desired temperature settings
- Monitors temperature of process tubes to ensure that low/high temperatures are maintained during media conveyance
