3281-F500 Fresh Water Sender - 500mm
3281-F1000 Fresh Water Sender - 1000mm
3281-F1500 Fresh Water Sender - 1500mm
3281-F2000 Fresh Water Sender - 2000mm




The 3281W NMEA2000 Fresh Water Level Sender will provide a ±2% accurate fresh water tank level to the NMEA2000 marine network and reports it's level in 1% increments.

It is robustly constructed in stainless steel with no moving parts to stick or fail in service. It is easily cut to length to suit tank depths from 200mm to 2 metres and is self calibrating at power on.

The Tank Sender can store an alphanumeric Tank Name and Tank Shape Calibration data so that displays on the network can show the tank name and it's remaining capacity in Litres, US Gallons or in Gallons.

It is easily fitted in the fresh water tank into a 1.25" BSP threaded hole. It can also be attached to the industry standard SAE 5 bolt fitting by using the 5 Bolt to 1.25" BSP Mounting Ring supplied.



Up to 16 Fresh Water Tank Level Senders can be connected to a single network and the sender number is simply selectable at installation by means of the small rotary switch.

It will be certified to the NMEA2000 network standard and attaches to the network using a single "Micro" plug. It draws less than 50mA from the network.

It comes complete with a full installation and operation manual, tank gasket and combined power and signal cable. It takes power from the NMEA2000 network and requires no additional wiring.

NOVA-II Spectrometer


Overview:

The heart of the OMA analyzer series is the nova-II spectrometer. Its diode array contains 1,024 photodiodes, each designated to detect a specific wavelength. Collecting light intensity data from all these diodes simultaneously, the nova-II continuously produces full, high-resolution spectra of sample absorbance.

In engineering a spectrophotometer, higher light transmittance means more robust data. This was our guiding principle in designing the nova-II; we set out to achieve maximal light throughput while retaining an extremely stable, solid state build. The use of a dispersive holographic grating erases the need for multiple focusing mirrors (as found in Czerny-Turner models). Having fewer reflective elements reduces both stray light and incident light loss--manifesting as a very high signal-to-noise ratio.

To learn about the conceptual basis of the nova-II and flow cell, see Principle of Operation: UV-VIS-SW-NIR Absorbance in the Concepts section.

*Some applications may require deuterium or tungsten light sources.

Applications:

The nova-II is the core technology behind our flagship OMA series, as well as the TLG-837 and TSA-100 systems. With broad spectral response (190-1100nm) and ultra-fine wavelength resolution, the nova-II packs the capacity for multi-component analysis from the low ultraviolet range all the way up to NIR
