The Ashcroft G-Series temperature switches feature a SAMA Class II vapor pressure thermal system. This system provides quick, accurate response to process temperature changes with minimal ambient temperature effects. This is inherent in the design due to the precise relationship between temperature and pressure according to the vapor pressure laws. A wide selection of sensing bulb and armored capillary lengths are available. The vapor pressure system design features small bulb sizes, making installation easy and cost effective.

All models feature ±1 percent of span set point repeatability with very high over-temperature ratings. These standard designs perform well in applications where shock and vibration could be a problem and should be used with Ashcroft thermowells for bulb protection and ease for installation and maintenance.

Application Notes

Here's how some of our customers used this product.

Preventing Boiler Stacks from Overheating

The Background: The customer is a large industrial plant that needs a solution that provides protection against overheating the boiler stack. If the stack temperatures exceed 750˚F, the burners must be shut down to avoid damaging the equipment.

The Problem: The high temperatures encountered at this plant are outside the range of many temperature switches or limit controllers.

The Solution: The customer selected the Ashcroft G Series Temperature Switch which is ideally suited for this application. The G Series is available in temperature ranges up to 750˚F and has a remote mount option so that it can be mounted in the burner cabinet for easy troubling shooting and resetting of the control.
