Pressure Gauge

Our pressure gauges (mechanical pressure measuring instruments) for gauge, absolute and differential pressure have been proven millions of times over. For the optimal solution for the widest range of applications, there is a choice of measuring systems in Bourdon tube, diaphragm element and capsule element technologies. The pressure gauges cover scale ranges from 0 … 0.5 mbar to 0 … 6,000 bar and indication accuracies of up to 0.1 %. For the various requirements in industrial and process instrumentation there are pressure elements from copper alloys, stainless steel or special materials.

Process Control

Process Control is the automatic control of an output variable by sensing the amplitude of the output parameter from the process and comparing it to the desired or set level and feeding an error signal back to control an input variable— in this case steam. A temperature sensor attached to the outlet pipe senses the temperature of the water flowing. As the demand for hot water increases or decreases, a change in the water temperature is sensed and converted to an electrical signal, amplified, and sent to a controller that evaluates the signal and sends a correction signal to an actuator. The actuator adjusts the flow of steam to the heat exchanger to keep the temperature of the water at its predetermined value.

Instrumental Temperature gauges Service

Temperature gauges measure the thermal state of a homogeneous substance. The measuring system must be brought as closely together as possible with the body to be measured. The most widely used measuring methods rely on temperature-dependent physical and material characteristics.

Bimetal temperature gauge

Bimetal temperature gauges operate with a measuring system in the form of a helical or spiral tube. The measuring system consists of two sheets with different expansion coefficients, which are inseparably joined. The mechanical deformation of the bimetal strips into the tube shapes mentioned above results in a rotational movement, caused by temperature changes. If one end of the bimetal measuring system is firmly clamped, the other end will rotate the pointer shaft. Bimetal temperature gauges are available with a scale range of -70 … +600 °C in accuracy classes 1 and 2 in accordance with EN 13190.

Expansion temperature gauge

An expansion temperature gauge consists of a temperature sensor, a capillary and a Bourdon tube. The measuring system itself is filled with a liquid. If the temperature changes, the internal pressure of the thermometer will change as well. The pressure is transferred via a tube to a pointer shaft and thus the temperature value is indicated on the scale. Using capillaries from 500 to 10,000 mm long, measurements can also be taken from remote measuring points. The scale ranges for expansion temperature gauges lie between -40 … +400 ° C with class 1 and 2 accuracies in accordance with EN 13190.

Gas-actuated temperature gauge

With a gas-actuated temperature gauge the stem, the capillary and the Bourdon tube are joined together into one unit. The instrument is filled with inert gas. If the temperature changes, the internal pressure will also change. The pointer is moved by the action of the pressure via a measuring tube. To compensate for the ambient temperature, a bimetal element is mounted between the movement and the measuring tube. Gas-actuated temperature gauges are available with scale ranges between -200 … +700 °C in accuracy class 1.

Machine glass temperature gauge

These temperature gauges are suitable for the monitoring of temperatures in gases, vapours and liquids in vessels and pipelines. The thermometer is housed in a case with a cutout for the scale display. Machine glass thermometers are often used with a V-shaped case.

 

Transducer & Contractor

Accurate instrumentation systems measure variables such as temperature, flow, angle, force, and displacement. One important element of many modern, scientific instrumentation assemblies is a transducer are devices that are often employed in automation, measurement, and control systems.

A transducer is any device that converts one form of energy into a readable signal. Many transducers have an input that is then converted to a proportional electrical signal. Common inputs include energy, , light, , position, acceleration, and other physical properties.

The output obtained from transducers is always in the electrical form, which is proportional to the measured quantity applied to the device. For example, a  will convert an applied force to an electrical potential that is equivalent. The force is measured with strain gauges in a Wheatstone Bridge configuration. The strain gauges measure electrical resistance changes in response to an applied force. The signal from the strain gauge passes through signal conditioning, or amplification, before being output as an electrical signal to a form of Data Acquisition.
