5.3 million switching operations later…
East Syracuse NY, USA?? –?? Measurement and control technology from JUMO has been synonymous with exceptional quality and reliability for 66 years.
A test conducted in the company’s test laboratory has now proven just how durable its products really are.
During the test, ten EM panel-mounting thermostats with a temperature controller function and a switching capacity of 24 V/0.1 A performed mechanical switching operations.
The aim was to determine the service life of the thermostat on the basis of an average switching operation per minute.
The results were a surprise!
Not a single thermostat failed after 5.3 million switching operations!
For use in continuous operation, this result translates into a service life of ten years.
Time and capacity restrictions meant that the test was stopped at this point for the time being. However, there are other upcoming test series for this range.
JUMO panel-mounting thermostats enable efficient control of thermal processes without the use of auxiliary power.
The temperature controller operates according to the fluid expansion principle, whereby the filling liquid in the measuring system expands when warmed and a microswitch is actuated via transmission mechanics.
In addition to the temperature controller version, the thermostat is also available as a temperature monitor or temperature limiter. A safety temperature monitor and a safety temperature limiter (which are equipped with a self-monitoring function) may also be used to meet more stringent requirements.
As such it is possible to protect any plant component against potential damage.
EM panel-mounting thermostats are used in the rail industry in order to monitor and control air curtain systems in trams, for example. Here, the devices are used to control two different heating levels.
The EM series is also used to protect against frost in fresh water and waste water tanks in trains. The thermostat does this by activating a heating mat as soon as the external temperature falls below 5 ??C.
EM panel-mounting thermostats are also used in numerous other industries.
JUMO is a worldwide trademark for measurement and control technology. The company was established in 1947 by Moritz Kurt Juchheim in Fulda, Germany. (See company history) In just a few decades, JUMO has grown from modest beginnings to an internationally successful company, with offices and representatives across the globe. JUMO began the United States subsidiary, JUMO Process Control, Inc., in 1984. Initially focusing on support and service for their customers with exports to the US, JUMO soon proved to be a valuable ally to US manufacturers as well. In 2005, JUMO USA further expanded to develop a manufacturing facility, becoming a well-established provider of measurement and control instrumentation to manufacturers across the United States and Canada. To better serve customers in Canada, JUMO opened a subsidiary in the Toronto area in 2012.
