Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms. They often include rate indication features and totalizer, data logger, and chart recorder capabilities. Humidity controllers that provide heating and cooling control are also available. Multi-functional products can be used to control thermoelectric, thermistor, or thermocouple heaters; or to control resistance temperature detectors (RTD), resistive heaters, or heating elements. Typically, suppliers indicate whether humidity controllers are designed for use liquids, solids, powder, gases, air, or steam. Some humidity controllers have a printed circuit board (PCB) form factor. Others are designed for mounting in a rack, on a DIN rail, or on a wall, chassis, enclosure or cabinet. Stand-alone process controllers are benchtop or floor-standing units with a full casing or cabinet and an integral interface. |
Products & Services Related to Humidity Controllers
Batch Controllers
Batch controllers maintain the correct size of a discrete batch of process material, such as the volume of a liquid. They are often interfaced with sensors such as load cells, or with volumetric flow meters.
Flow Controllers
Flow controllers monitor and maintain proper humidity levels in environmental test applications, or in other areas such as food storage or electronic room regulation.
Level Controllers
Level controllers monitor, regulate, and control liquid or solid levels in a process.
pH Controllers
pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application.
Pressure Controllers
Pressure controllers accept input from pressure sensors, transmitters, gauges, and other devices and subsequently control adjustment to the pressure to maintain or achieve the desired pressure level.
Universal Process Controllers
Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.
Web Controllers
Web controllers maintain control functionality over processes with web or sheet rollers. Control functionality includes maintaining tension of the web, centering on the track, and material feed rates.
