Company Background

The company STS was founded in 1987 by four engineers. Since then the company has grown and strengthened its position in the pressure, level, logger and telemetry market.

All STS products are produced in Sirnach Switzerland. All stages of transducer manufacturing are completed at the STS premises which includes; assembling of the sensors, testing, calibration and service. The STS sensor design is modular so that a large variety of pressure ports, electrical connectors, output signals and any pressure range between 50 mbar and 1000 bar can be selected to allow a customer to adapt the specification to their particular application requirements.
