Technical Datasheet 9700 Series Analogue Transmitter Submersible Hydrostatic Level Transmitters Model: 9790 - Flange Mounted Key Features • Accuracy ± 0.1% of calibrated span Ceramic capacitive sensor Fully submersible IP68 / NEMA 6P Product applications Reverse polarity protection Dedicated marine version wide range of applications in: Series Overview The 9700 Series range of tank level transmitters from Delta-Mobrey provide an accurate level measurement solution where in-tank problems such as foaming, vapor layers, and temperature gradients makes difficult the use of other instrumentation. Each transmitter version gives a high performance, has good long term stability, and is virtually maintenance free. Ceramic Capacitive Sensor (CCS) provides a “flush” diaphragm, avoiding the risks of sensor clogging. 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 Water Treatment Marine Market The choice of models available ensures that the Delta Transmitter is suitable for use in: Corrosive atmospheres Resistant to chemical attack Other products Other products we can offer: Delta Mobrey’s offers fast, efficient and knowledgeable support when and where you need it.

Note: Pmax values are shown in PSI according to Intrinsically Safe CSA approved documentation. In brackets are shown the correspondent limit in ftH2O and mH2O. Note: The glanding system used ensures absolute in-tegrity of the Polyurethane IP68 / NEMA 6P rating. All cable used include venting Fluorinated ethylene-propylene (F.E.P ) capillary. For humid environments or sea water applications, bellows must be used (contact Delta Mobrey). Cable Length Unit Note: the instrument is fixed range type.

Custom configuration of actual range (customer to specify with order) Installation The 9700 is available in both submersible versions and externally mounted (floodable) versions. The housing contains the capacitive ceramic sensor and the electronics circuit board, all the components needed to produce an accurate and reliable measurement of the process. The glanding system used with the submersible versions ensures absolute integrity of the IP68 / NEMA 6P rating. IP68 / NEMA 6P units are generally factory fitted with the required length of vented cable fitted. Technical Data Metrological...
