Frequently Asked Questions
YOUR QUESTIONS, ANSWERED.
One of the standout characteristics of an exposed cap is its’ use of a black exposed disc. This disc serves as a crucial element in sensing temperature fluctuations swiftly, enabling the switch to respond rapidly to environmental changes. This quick thermal response is especially important in applications where precise temperature control is paramount, such as in thermostats, industrial control systems, and appliances. The exposed caps are available for all non-epoxied snap disc thermostats within the Senasys catalog.

One of the key advantages of gold contacts is their significantly lower contact resistance when compared to high-current silver contacts. This low resistance translates into improved electrical conductivity, allowing for smoother and more reliable signal transmission. This is especially important in applications where even the slightest interruption or distortion in the signal could lead to critical errors or malfunctions.

When it comes to temperature monitoring, precision is key. The standard flange mount plays a vital role in achieving this precision by minimizing the distance between the sensor and the area being measured. This reduced gap ensures that temperature fluctuations are detected and recorded with remarkable accuracy, making it an indispensable tool in industries where temperature control is critical.
