Description
16 micron 0.4mm Membrane Hydrophone – Order Code UT1604
The hydrophone is supplied with a PA submersible preamplifier, which is inserted into the base of the hydrophone mounting ring and provides 8dB of gain and 50 OHM output. The preamplifier is powered through the DC Coupler from a 28V power supply. (See DC Coupler for more information).
Technical Specifications

| Cable: | The preamplifier is terminated with 1.5m of RG 174 cable and SMC connector which connects to the DC Coupler |
| Active Sensor Diameter: | 0.4mm |
| Typical Sensitivity: | 30-35mV/MPa at 3MHz |
| Sensitivity Tolerance: | Sensitivity variation between individual membranes is approximately +/-3dB |
| Typical Frequency Response: | Flat(+/-2dB): over the range 1-30MHz A “flattening amplifier is not required as this hydrophone satisfies IEC standards |

Warranty: membranes 12 months against defective product but not damage caused by user. If a warranty claim is made on devices that have been calibrated at NPL, London, a charge will be made for the used part of the calibration (e.g. in the event of failure of a membrane at three months the charge for recalibration at NPL is 25% of the calibration charge).
The membrane hydrophone can be used with the Precision Acoustics Hydrophone Signal Amplifier (Order Code MA2) which reduces noise and applies x5 gain (optional) and is designed to be used with a UT series membrane hydrophone.
