Brand Introduction
GHM GROUP Solution: Flexible Developer Library!
More than 40 experienced experts from six competency centers bring their expertise in their respective fields to a multidisciplinary team that can quickly, flexibly, and accurately develop products or make adjustments to meet customer needs.
The transformation of the 21st century has brought enormous challenges to companies around the world. But this development also provides hopeful opportunities. Because it is precisely in the past few decades that the trend has developed into a driving force for innovation. GHM Group is a participant in this dynamic market development. As a medium-sized company, we are committed to transforming these trends into marketable products and solutions that are faster than other products. Accelerating speed through flexibility, like almost all industrial fields, measurement and control technology also requires innovation, high quality, and service. The innovation cycle is getting shorter - the speed of implementing and adapting to new requirements must be getting faster. Our management is facing this challenge with a consistent strategy.

business domain
Many medium-sized companies are usually localization oriented and must also adapt to major trends. In order to meet market demand, it is necessary to bundle local capabilities. The motto is: Think about local development and produce quickly.
Nowadays, strategic planning and adjustment are important management elements and were established with us last year. GHM Group is now divided into three strategic business areas. Further segmentation is not only for clarity, but also aimed at promoting the professional knowledge of our employees. A distinction has been made between sensor technology and electronic products in the "industrial" business field. In 'Environmental Measurement Technology', we divide our products into meteorological and mobile measurement devices. At the same time, we provide products for the business areas of "signal conditioning and data acquisition" and "calibration and service", including product adjustments for customers.
product scope
MARTENS industrial automation components, MARTENS signal converters, MARTENS transmitters, MARTENS, MARTENS relay modules, MARTENS solid-state relays, MARTENS temperature controllers, and MARTENS display instruments from Germany.
MARTENS was founded in 1988 and has over 20 years of rich experience in the fields of measurement, control, and process measurement. All products are developed and produced locally in Germany, including digital displays, signal converters, sensors, and analytical instruments. Almost every physical or electrical quantity can be measured. MARTENS can provide customers with customized non-standard products. Products can be designed from the perspective of customer applications.
STL4896 Product Introduction
Parameters
STL4896-1:
Pt1003 wire -100.0 . + 600.0°C
STL4896-5:
J(Fe-CuNi)-100.0 . . + 800.0°C
K(NiCr-Ni)-150 . . + 1200°C
N(NiCrSi-NiSi)-150 . . + 1200°C
S(Pt10Rh-Pt)0..1600°C
Notes:
The STL4896 safety temperature limiter must be installed in a switchgear with a protection level of at least IP40; One or more strain relief cables must be provided for the temperature sensor connection; To protect the internal equipment fuse of STL4896, it is recommended to use an external fuse (max)1.6 A medium delay) fixed monitoring current circuit. If the internal fuse trips, the equipment must be sent to the factory for repair!
Application scenarios: Suitable for important places such as high-rise buildings, airports, power stations, and commercial centers that require fire, explosion, and moisture prevention.
