• Wide useable frequency
• Long term stability
• Omnidirectional in all planes
• Resistant to high static
pressure
• Individually calibrated
TC4037
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, tempera-
ture.
The mounting support is equipped with sealing o-rings that allows for convenient

Encapsulating material:
Special formulated NBR
Metal body:
TC4037-2: Aluminum alloy Al Mg1Si
TC4037-3: Promet 12 CuSn 12 Tin bronze
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 Aluminium alloy Al Mg1Si – If installed on a metal housing it is
important that the housing is made of a similar material.
