The 9700 Series range of tank level transmitters from Mobrey provide the measurement solution where in-tank problems such as foaming, vapor layers, and temperature gradients prohibit the use of other instrumentation. The 9700 Series transmitter is designed to perform in the extreme conditions of today’s industrial measurement applications. Transmitters are available in both submersible and externally mounted (flood able) versions. Each transmitter version gives a high performance, has good long term stability, and is virtually maintenance free. A ceramic sensor ensures precise and reliable measurement with an accuracy of better than 0.1%.
At the heart is a Ceramic Capacitive Sensor (CCS). This pressure sensor provides a “flush” diaphragm, avoiding the risks of sensor clogging and ensures an extremely low hysteresis, minimal output drift, and high repeatability. The sensor is manufactured using an aluminium oxide ceramic and provides outstanding resistance to chemical attack. The measuring range is determined by the ceramic thickness, which is precisely controlled during the manufacturing process. The sensor works like a capacitor with electrode surfaces on the inside comprising one measuring and one reference capacitor. The surfaces of the capacitors are gold-plated and linked to ASIC electronics. These electronics generate a signal proportional to the applied pressure, which is sent to the 4–20 mA signal conditioner.
