Load Cells Used for Weighing Applications in Industrial Control

Load Cells Used for Weighing Applications

Physical science principles are integrated with technology and engineering to build devices critical to modern high speed, high accuracy system operation in industrial process monitoring and control. 

A load cell measures things ranging in size from very small to extremely large and is an essential component of weighing materials and equipment. Their usefulness applies to many process weighing applications across various industries.

In essence, a load cell is a force measurement device that acts as a transducer, transforming force into a unit of quantifiable electrical output in a predictable manner. While there are many different types of load cells, the strain gauge-based cell is the most used in many industries. These strain gauge cells typically have an accuracy range of 0.03 percent to 0.25 percent. Pneumatically based load cells are appropriate for circumstances demanding intrinsic safety and optimal hygiene. There are also hydraulic load cells that run without the requirement for a power supply for regions without a power grid.  These load cells operate on the same principle: a force acts on the cell, which then computes as a value. The value is processed to get an indicator of weight in engineering units. 

The deformation principle applies to strain gauge cells, where highly minute amounts of deformation, directly related to the stress or strain applied to the cell, are produced as an electrical signal with a value proportional to the load applied to the cell. The operating concept enables the creation of devices capable of providing accurate, precise measurements of a wide range of industrial products. 

Load cells' advantages include their endurance, accuracy, and flexibility to a wide range of applications, all of which contribute to their utility in a wide range of industries and applications.

Thermal Flow Meters with Superior Technology

Fox Thermal Flow Meters

PowerPro™ Sensor

Used in Fox Thermal Models FT2A and FT3, the Fox Thermal PowerPro™ Sensor operates at a higher power level than other competitive thermal technologies, providing better response time and wider turndown. Compared to a typical Differential Pressure(DP) type flowmeter (see inset), thePowerPro™ sensor offers better low flow or low-end sensitivity. The PowerPro™ sensor also provides exceptional accuracy at high velocities - up to 60,000 SFPM air.

DDC-Sensor™ Technology

The Fox Thermal DDC-Sensor™ is a new state-of-the-art sensor technology used in the FT1, FT4A, and FT4X flow meters. The DDC-Sensor™ is a Direct Digitally Controlled sensor that is interfaced directly with the microprocessor for more accuracy, speed, and programmability. Like thePowerPro™ Sensor, the DDC-Sensor™accurately responds to changes in process variables (gas flow rate, pressure, and temperature), which are used by the microprocessor to determine mass flow rate, totalized flow, and temperature.

Constant Temperature Differential 

Fox Thermal flow meters use a constant temperature differential (ΔT) technology to measure air and gases' mass flow rate. The thermal mass flow sensor consists of two Resistance Temperature Detectors (RTDs). The sensor elements are constructed of a reference-grade platinum wire around ceramic mandrels inserted into a stainless steel or Hastelloy tubes.

The reference RTD measures the gas temperature. The heated element is kept at a constant temperature, and the instrument electronics measure the gas flow's cooling effect. The electrical power required to maintain a constant temperature differential is directly proportional to the process gas's mass flow rate. The microprocessor then linearizes this data to deliver a 4-20mA output signal.

Valves for the Food and Beverage Industry

Valves for the Food and Beverage Industry

Valve selection in food and beverage processing is essential for maintaining quality and consistency. Does the application require the valve to contact the product directly, or is it indirectly influencing the process? Does the valve require special cleaning procedures or located away from areas where contamination is a concern?

Food and beverage industry valves are used in a wide range of applications to regulate steam, hot water, refrigerants,  CIP cleaning media, or gases required for temperature control during sterilization, autoclaving, carbonation, or pasteurization of different products. They are also found in fermentation, smoking, cleaning, drying processes, freshwater supply, brine, or wastewater.

Schubert and Salzer manufacturers a wide range of valves used in food and beverage processing. Their products include:

  • Sliding-Gate Control Valves
  • Aseptic Right Angle Valves
  • Pinch Valves
  • Shut off Valves

Probe Type Tunable Diode Laser Spectrometer TDLS8100

Yokogawa’s new TDLS8100 continues to house all of the industry’s leading features from the TDLS8000 but now only requiring a single-flange installation. An in-situ measurement with a probe removes sample extraction and conditioning requirements and is ideal for various aggressive process conditions.

Built upon Yokogawa’s second generation of TDLS analyzers, the platform still retains its improved reliability, ease of installation, and reduced maintenance requirements. Still, it now does so with a lower total installed cost for O2, CO/CH4, and NH3 measurements.
