Spherical Reference Hydrophone
The TC4037 hydrophone sensor module provides a differential balanced output signal. It has been designed especially for operation with a differential preamplifier.
The use of differential sensor signals offers advantages such as limitation of DC offset and fluctuation. It further adds 6dB more sensor sensitivity, reduces noise distortion and makes the sensor less sensitive to vibration, temperature. The mounting support is equipped with sealing o-rings that allows for convenient waterproof mounting.
NBR means Nitrile Rubber
The NBR rubber is first of all resistant to sea and fresh water but also resistant to oil. It is limited resistant to petrol, limited resistant to most acids and will be destroyed by base, strong acids, halogenated hydrocarbons (carbon tetrachloride, trichloroethylene) nitro hydrocarbons (nitrobenzene, aniline), phosphate ester hydraulic fluids, Ketones (MEK, acetone), Ozone and automotive brake fluid.
Metal body: TC4037-2 aluminum alloy Al Mg1Si – If installed on a metal housing, it is important that the housing is made of a similar material.
