The high-pressure transducers of the 7LHPTi series have a robust housing made of titanium, giving them optimum long-term stability for a range of OEM applications. The metal diaphragm is welded on front-flush and gap-free, separating off the piezoresistive pressure sensor, which is made of silicon, from the measuring medium. Every pressure transducer is measured over the entire pressure and temperature profile and is supplied with a detailed calibration sheet.

The differential pressure transmitters of the PRD-33X series are designed for accurate measurements in low pressure ranges with very high overload on both sides. In addition to the differential pressure sensor, which may only be exposed to gases at its rear face, the devices have an additional absolute pressure sensor that measures the line pressure. Both measured values are output via the digital RS485 interface and are the ideal basis for cryogenic tank monitoring.

The 22DT series has been specially developed for use in bivalent vehicles (volume flow measurement when running on natural gas) and is homologated for the automotive industry. However, it also has other industrial applications. The NTC or PT temperature sensor located directly beneath the steel diaphragm reacts more quickly to temperature changes thanks to its special design. The pressure transmitters are protected against electromagnetic fields up to 200 V/m and output the measured values as a ratiometric 0,5...4,5V analog signal. The connections of the temperature sensor are fed out directly.

The pressure transmitters of the 23SY-Ei series are designed for elevated requirements in industrial applications. Thanks to its modular concept, this series is highly flexible and makes it possible to realise customer-specific requirements in very little time. The sophisticated compensation circuit makes it possible to specify a narrow total error band. Intrinsically safe – suitable for use in explosive atmospheres.
