The model 111 pressure gauges are based on the proven Bourdon tube measuring system. The deflection of the Bourdon tube is transmitted to a movement and indicated. The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges. Due to the high variance, the instrument is suitable for use in a wide range of applications within industry. For mounting in control panels, the pressure gauges can, depending on the process connection, be fitted with a surface mounting flange or with a triangular profile ring and mounting bracket. The standard version of the model 111 is manufactured, cost-optimised on modern production lines, in volumes of several million instruments per year.

The model A43 bimetal thermometer was developed as a standard version for simple temperature indication in heating applications. Its modular design enables a multitude of combinations of case materials, nominal sizes, scale ranges and stem lengths. This ensures that the basic dimensions are maintained. The standard scope of delivery of the model A43 includes a thermowell. The thermowell can be operated with an operating pressure up to a maximum of 6 bar. The model A43 is manufactured to tolerance class 2 in accordance with EN 13190 and thus offers the required indication accuracy for heating technology.
