The 368 Hydrastat is designed for temperature sensing from -40°F to 700°F, providing accurate readings for a variety of applications. The cup size of the diaphragm determines the maximum movement within the specified temperature range. When selecting the appropriate Hydrastat, the relationship between bulb dimensions & the desired temperature range must be considered, as one of these dimensions will vary based on the necessary movement at the operating temperature.
