200ULH On-Camera UHF Wireless Handheld - Bodypack System

Manufacturer Part Number: 200ULH

The 200ULH is a complete dual-channel wireless system that consists of the 200UPR receiver and one each 10HT handheld transmitter and 10BT bodypack transmitter.

The new 200UPR receiver allows the use of two wireless transmitters at the same time. It features twin-antennas, a 3.5mm -64dbB 2-channel mic level output jack, two recessed On/Off switches, two Power On/ Signal Received LED and 2 sets of channel selectors to set the desired frequency for each receiver. Using crystal-control and PLL synthesis the 200UPR operates for better than 8 hours on 6 "AA" batteries. The receiver comes with a "hot-shoe" mount, a 2-channel 3.5mm to 3.5mm output cable and a 2-channel 3.5mm to twin XLR cable.

Included is one 10HT UHF handheld microphone which is designed to work seamlessly with the on-camera 200UPR receiver. The new mic features Azden's special surface coating to reduce handling noise. Using an electret-condenser unidirectional element, the 10HT is designed with low-noise PLL circuitry to allow the user to select any one of 63 UHF channels to assure interference free reception in the 794-806MHz range.

The new microphone uses two commonly available alkaline AA batteries to operate for better than 8 hours.

Also included is the10BT body-pack transmitter supplied with the Azden EX-503 omni-directional lapel microphone and a metal belt-clip. In addition to the 3.5mm mic input jack the transmitter has a Power On switch with an associated LED a separate Standby switch for audio muting and a set of channel selector switches. The 10BT runs better than 8 hours on a single 9V battery.

High-Quality 188-Channel UHF Mic Systems from Azden

The Azden product line contains a full spectrum of on camera UHF mic systems. The biggest technological difference between these and the less expensive VHF systems is in the way various radio **s travel. VHF **s tend to travel in a straight line, and when they encounter obstacles like chairs and tables, and even people, they bounce , or reflect, off these objects. The result can be noise (hissing sound), or drop out. The drop out is caused by the original ** and the reflected ** in effect canceling each other out for an instant. Either of these factors can adversely affect your soundtrack. On the other hand, UHF **s tend to travel either through or around these same objects, so there are no reflections, and noise and dropouts are virtually eliminated. This is the biggest advantage that UHF has over VHF. Add this to the to the fact that these systems come with 188 field adjustable channels, and the potential for interference is virtually eliminated.

Features
• Single Channel Camera-Mount UHF receiver (305UPR)
• Discrete 2-Channel Camera-Mount UHF receiver (325UPR)
• 188 User-Selecta

电磁流量计误差产生原因分析与实例剖析
电磁流量计优点很多，应用非常广泛，但若选型、安装、使用不当，将会引起误差增大，示值不稳定，甚至表体损坏。本文详细阐述了电磁流量计误差产生的原因，总结多年的经验教训，得出电磁流量计误差产生的原因主要有下面几个方面。一、电磁流量计管内液体未充满由于背压不足或流量传感器安装位置不良，致使其测量管内液体未能充满，故障现象因不充满程度和流动状况
金属管浮子流量计常见问题及处理
金属管浮子流量计在不同压力和温度下显示的值一样吗,为什么? 气体肯定不一样，不同温度压力下气体密度不同，产生的浮力也不同。液体基本一样，液体密度受温度压力影响不大。金属管浮子流量计显示屏上显示STOP是怎么回事? stop的意思是你的浮子没动了，是不是管道堵塞了。。。因为浮子流量计对流体稳定性要求很高。安装后经常性上下波动是正常的. 金属管浮子流量计的RP是什么? 始位置，就是零位了为什么
金属管浮子流量计市场需求
由于我国制造业的高速发展，TK-JSL金属管浮子流量计拉动了对自动化仪表与控制系统的需求，我国新上市的大型项目所用自动化仪表和控制系统的先进程度已经处于世界良好水平，金属管浮子流量计的不断需求将拓展市场的发展道路。 TK-JSL金属管浮子流量计除去了以往流量计在安装时的繁琐，同时还延续了以往其他流量计的测量精确度,工作可靠，维护量小，寿命长，方便快捷体积小都是金属管浮子流量计不可被忽视的优点。这
如何让流量计安全过冬
冬后，因常出现环境温度过低时就会发生冻结、凝固、析出结晶等现象。为此，必须对流量计和流量计测量管线进行防冻处理，需要伴热保温的对象主要有安装在流量计保温箱内的变送器，外浮筒式液位变送器或其它形式的露天安装的液位变送单元，压力，差压，流量等流量计的检测管线和测量管线。通过选型或其他方式避免此类事故发生。采取的措施通常有：选型，保温伴热，维护(点巡检、排污)等。
