Chromatographs

Chromatographs are used to separate and identify individual components in a mixture. They work by passing a sample through a column containing a stationary phase and a mobile phase, which separates the components based on their physical and chemical properties.

Mass Spectrometers

Mass spectrometers are analytical instruments that measure the mass-to-charge ratio of ions in a sample. They can be used to identify and quantify individual substances in a sample and are commonly used in the biotechnology and pharmaceutical industries for drug discovery and development.

Pressure Measuring Instruments


industrial-instruments,Pressure Measuring Instruments,thqPressureMeasuringInstruments

Pressure measuring instruments are devices that can monitor and record pressure changes in a system. They play an important role in many industrial applications, such as in pipelines, pumps, water treatment plants, and refineries. There are several types of pressure measuring instruments, including:

Bourdon Tube Gauge

The Bourdon gauge is the most commonly used pressure gauge in industrial applications. It consists of a curved, flattened tube that is connected to the system of interest. As pressure increases, the tube straightens, and this movement is translated into a pressure reading on the gauge. These gauges are relatively inexpensive, reliable, and can measure pressures up to 10,000 psi.

Differential Pressure Gauge

A differential pressure gauge measures the difference in pressure between two points in a system, such as across a filter or pump. It utilizes a diaphragm, bellows, or Bourdon tube to convert the differential pressure into a visual reading on the gauge. Differential pressure gauges are commonly used in HVAC systems, clean rooms, and liquid level measurement.

A bimetallic strip thermometer utilizes two different metals that are bonded together and expands and contracts at different rates. The strip bends due to the difference in thermal expansion, which is measured by a pointer or digital display. They are commonly used in HVAC applications, cooking equipment, and refrigeration systems.

Infrared Thermometer

An infrared thermometer operates by detecting the radiation emitted by an object. They are easy to use and can provide non-contact temperature measurements for moving or hazardous objects. They are commonly used in automotive, food, and chemical industries.

Thermocouple

A thermocouple is a type of temperature sensor that measures the voltage difference between two dissimilar metals. The voltage reading correlates to a specific temperature based on a calibration chart. Thermocouples are rugged, reliable, and widely used in industrial processes, including furnaces, boilers, and kilns.

Calibration and Maintenance of Industrial Instruments
