16 micron 0.4mm Membrane Hydrophone - Order Code UT1604 (formerly UC1604)
Description
For most MHz ultrasound pressure measurements, where wide bandwidth, smooth frequency response and small active area are required, this hydrophone is recommended.
Specification
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).
| Output Impedance: | 50 Ohms |
| Sensor Material: | Single layer of 16 micron thick gold PVdF film |
| Mounting Ring Dimensions: | 100mm diameter 10mm thick |
| Membrane Diameter: | 80mm |
| 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 |
This specification is subject to change without notice.
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.
