There are a number of elements that go into designing a bulb and capillary thermostat switch. The most important elements are bulb diameter and length restrictions, capillary tube length, and switching temperature. All of our bulb and capillary thermostat switches are…
Throughout our website we use the verbiage limit and control, or fan. It is not always clear to users what temperature switch to use for certain applications. Even though fan and limit switches are put together in our documentation,…
For the purpose of our discussion we will use the word oven to denote any heated chamber used for cooking, curing, processing paint or adhesives, laboratory control and forming. In any oven, especially commercial ovens, there are two capillary thermostat…
Not all Bulbs, Probes and Capillary Tubes use a fluid fill, some use a gas. There are a large number of different fluids and gases used. This is based on: What material is being sensed for temperature Temperature range of the…
STEMCO, a division of Senasys, Capillary Switches stand out from other capillary switch manufacturer’s because they are temperature compensated. A capillary switch should be temperature compensated to adjust the switch’s performance when changes in temperature occur. For instance, a capillary…
Our different test procedures include pressure and stress the capillary diaphragms over a period of time, and multiple temperature tests. These numerous procedures will tell us if a leak in the capillary diaphragm assembly exists. Once the testing is complete,…
Senasys capillary thermostats at 100% tested and sold across the globe to original equipment manufacturers. Before leaving our facility, these switches undergo submersion testing to verify the temperature which the switch operates. Our quality assurance team submerses 100% of the…
MORE ON OUR NEW D-SERIES DIGITAL SWITCH While we were working on the design of our new D-Series Digital Switch, we knew that we needed to find a reliable relay for switching the load on and off. During this process…
Coffee Makers Use Capillary Thermostats Did you know that one of our switches could be used to make that cup of coffee you are drinking every morning? Well, now you do. I am going to get you a little insight…
Senasys’ capillary thermostats are easily installed into equipment. The thermostat is available with a bottom mounting bracket that is assembled to the switch, or upon installation. To assemble the bottom bracket hardware to a capillary thermostat, follow the simple instructions.…
