Of course, hydroelectric power plants need to keep an eye on flow, level, temperature, and\u00a0pressure. But don’t forget about force, a key measurement as reservoirs are surrounded by rock and earth. There’s also the matter of instrument calibration, an essential aspect of plant safety and efficiency.<\/strong><\/p>\n\n

This force transducer by tecsis, a WIKA subsidiary, is placed between two adaptor plates to continuously record the clamping force. It immediately detects any changes in the pretension of the anchor.<\/p><\/div>\n \n

Geotechnics: Don\u2019t\u00a0Underestimate the Force<\/h2>\n

Hydropower plants work with water<\/a>, but the entire\u00a0facility is surrounded by rock and earth \u2013 thus the\u00a0importance of measuring geotechnic forces.<\/p>\n

By withstanding longitudinal and transverse force,\u00a0anchors are permanent or temporary constructional\u00a0elements that stabilize the subsoil. Therefore, plants\u00a0need to pay special attention to the metrological\u00a0inspection and monitoring of the pretensioning force\u00a0of anchors as load-bearing elements of a structure,\u00a0especially in the case of permanent anchors.<\/p>\n

What anchors do<\/h3>\n

Anchors secure foundations, protect slopes or\u00a0ceilings in tunnels, and attach railing posts to\u00a0the ground. The anchor is either inserted into the\u00a0drilled reinforcement or flush with the surface\u00a0and concreted, or it serves as a drill (self-drilling\u00a0anchor). Anchor heads are affixed using wedge\u00a0disks, anchor head plates (adaptor plates), and\u00a0domed nuts.<\/p>\n

\u00a0<\/h3>\n\n
\"Load

Anchors and force transducer are used to support slopes, secure foundations, monitor concrete conditions, and much more.<\/p><\/div>\n \n

Monitoring anchor force with force transducers\u00a0<\/h3>\n

When placed between two adaptor plates, a force\u00a0transducer continuously records the clamping force.\u00a0By measuring that force, users obtain the data\u00a0necessary to optimize safety and check planning\u00a0calculations, such as when terrain is moved for\u00a0structural or safety-related measures. If a change\u00a0in the anchor\u2019s pretension occurs, the transducer\u00a0detects it immediately and sends an alert so\u00a0appropriate action can be taken. For especially\u00a0inaccessible terrain, use autonomous systems that\u00a0do not require an external power supply.<\/p>\n

What else force transducers are good for<\/h3>\n

When constructing a hydropower plant, a force\u00a0transducer can do more than keep an eye on\u00a0geotechnical conditions. It can also monitor\u00a0concrete conditions during the building process.\u00a0<\/p>\n

Here\u2019s how: The ring force transducer is\u00a0prestressed on the reinforcing rod, against the\u00a0shuttering. When concrete is poured, it exerts a\u00a0high force on the shuttering. As concrete hardens,\u00a0that force gradually subsides. This is an efficient,\u00a0timesaving method of remotely monitoring the state\u00a0of concrete.<\/p>\n

Calibrating Instruments<\/h2>\n

With so many variables to monitor, instruments must be reliably accurate. WIKA makes\u00a0several calibration systems for testing and servicing pressure components.\u00a0<\/p>\n

CPG1500 <\/strong><\/a>is a precision digital pressure gauge that comes with an integrated data logger.\u00a0It is ideal for testing hydraulic systems and valves in power plants. Model CPG1500 combines\u00a0the accuracy of digital measurement technology with the simplicity of an analog gauge.\u00a0<\/p>\n

CPC6050 <\/strong><\/a>is a modular mobile precision pressure controller. This multi-channel\/multi-range\u00a0pressure system has been designed to test and calibrate a variety of pressure devices. It\u00a0features up to four temperature-compensated pressure transducers, an accuracy of 0.01%\u00a0FS, and barometric reference.<\/p>\n\n

The CPC8000 High-End Pressure Controller<\/p><\/div>\n \n

CPC8000 <\/strong><\/a>is a high-end pressure controller designed to automate the testing and\u00a0calibration of all types of pressure components. It features a large color LCD display and\u00a0easy, intuitive navigation. Operating pressure ranges from 5 psi to 6,000 psi, and each of\u00a0its three transducer modules is configured with its own calibration parameters.<\/p>\n
