Intelligent and powerful pressure sensor technology for the most demanding jobs: This is what the sensor and automation specialists from STW will be displaying at the Sensor+Test, June 11-13, Nuremberg.
At Sensor+Test, STW is presenting a comprehensive and modular range of sensors. Among other topics, the focus is on sensors for recording pressure and other media information. Thanks to digital interfaces, the M01 pressure sensors can simultaneously provide both pressure and media temperature as well as other status and diagnostic information. The M01 sensors can be used in a wide range of applications from low to high pressures, including pressures up to 2000 bar. They are compatible with the current SAE-J1939 and CANopen protocol specifications and utilize a newly developed 32-bit microcontroller platform, ensuring future viability and long-term availability.
The sensors also support the SENT protocol. In simple terms, SENT acts like the classic analogue transmission of measured values and transmits continuously, unidirectional and interference-free via a three-wire connection. In contrast to conventional analogue outputs, however, SENT can transmit a wide range of information simultaneously. This simplifies the condition monitoring of the machine or vehicle and offers particular advantages in safety-relevant applications. Pending damage or faults can be identified before the machine comes to a standstill. A plus in terms of safety and productivity for the machine operator.
In addition to the M01 sensors, STW will also be presenting pressure sensors for use in hydrogen applications such as fuel cell based vehicles. Hydrogen is one of the most demanding media for pressure measurement. Without specific countermeasures, the gas can diffuse into and through materials, including metals, resulting in a gradual decrease in sensor accuracy and malfunctions. At the same time, the penetration of hydrogen into a material can compromise its structural integrity and cause it to become brittle. To measure the pressure in hydrogen, STW has developed stronger measuring cell designs with substrates made of hydrogen-impermeable materials utilizing thin-film technology in combination with resistant but highly sensitive functional layers.
Like all products from the established German company, the sensor solutions are compatible with their open-source software platform openSYDE and can be parameterized, configured and monitored in a user-friendly way.
STW will be displaying their technology and solutions at Sensor+Test in Nuremberg, 11th to 13th of June, Hall 1, Stand 508.
