Precision Acoustic UT1604 0.4 毫米膜式水听器

Precision Acoustics Membrane hydrophone 0.4 mm

0.4 毫米膜式水听器

For most MHz ultrasound pressure measurements, where wide bandwidth, smooth frequency response and small active area are required, this hydrophone is recommended.

对于大多数兆赫超声波压力测量来说，当需要宽频带、平稳的频率响应以及较小的活动区域时，推荐使用这种水听器。

Overview 概述

16 micron 0.4 mm membrane hydrophone – order code UT1604

16 微米、0.4 毫米厚膜的水听器——订单代码：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 Ω output. The preamplifier is powered through the DC coupler from a 28 V power supply. (See DC coupler for more information).

该水听器配备了 PA 型潜水式前置放大器，该放大器被安装在水听器的底座中，能够提供 8 分贝的增益效果，并且输出阻抗为 50 欧姆。前置放大器的电源通过 28 伏特的电源连接器提供。(有关电源连接器的详细信息，请参见相关说明。)

Technical specifications

技术规格说明

* Precision Acoustics reserves the right to change the specification without notice.

* Precision Acoustics 保留在不另行通知的情况下更改规格参数的权利。

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).

保修政策：对于存在缺陷的产品，保修期为 12 个月，但用户自身造成的损坏不在保修范围内。如果设备在经过伦敦 NPL 校准后提出保修要求，那么将需要支付校准费用的一定比例作为补偿(例如，如果在保修期三个月后膜片出现故障，那么在 NPL 重新校准时的费用将相当于校准费用的 25%)。

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.

该膜式水听器可以与 Precision Acoustics 膜式话水听器号放大器(订单代码 MA2)配合使用。该放大器能够降低噪音，并提供 5 倍的增益效果(可选)，非常适合与 UT 系列膜式水听器一起使用。
