|
Diaphragm seals are isolation devices that separate a pressure instrument from the process media.
|
|
Diaphragm valves close by means of a flexible diaphragm attached to a compressor.

|
|
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.
|
|
Electric actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
|
|
Engineering consulting firms provide engineering services and expertise to companies in need of a specialized skill-set. Professionals in this category work with clients to define solutions to problems or to help determine and recommend the best course of action for a given initiative.
|
|
Flame detectors monitor and analyze incoming radiation at selected wavelengths.
|
|
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
|
|
Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow.
|
|
Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow.
|
|
Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service.
|
|
Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air.
|
|
HVAC controllers are used to monitor and control heating, ventilation and air conditioning (HVAC) systems in buildings. They monitor indoor environmental factors such as temperature and humidity, and control heating and cooling to maintain desired levels.
|
|
Industrial computers are similar to personal computers (PC), but they are intended for use on a factory floor or in other harsh environments.
|
|
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
|
|
Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation.
|
|
Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point.
|
|
Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids.
|
|
Machine shop services use machinery or equipment to perform custom removal of material to fabricate a finished part.
|
|
Moisture meters are used to measure the moisture content in bulk solids, liquids and gases.
|
|
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
|
|
pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP.
|
|
Pipe fittings include many components that connect pipe ends for in-line, offset, multi-port, and mounting configurations.
|
|
Pneumatic rotary actuators use pressurized air to rotate mechanical components.
|
|
Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications. Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers.
|
|
Pressure regulators are used to maintain a constant outlet pressure or flow.
|
|
Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line.
|
|
Pressure switches are actuated by a change in the pressure of a liquid or gas. They activate electromechanical or solid-state switches upon reaching a specific pressure level.
|
|
Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.
|
|
Rotameters are typically tapered glass tubes positioned vertically in the fluid flow. A float within the tube rides upward in relation to the amount of flow.
|
|
Solenoid valves are devices that use a solenoid to control valve activation.
|
|
Steam traps are automatic valves that release condensate from a steam space while preventing the loss of live steam. They also remove air and noncondensables from the steam space.
|
|
Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches.
|
|
Resistance temperature detector (RTD) temperature transmitters convert RTD resistance measurements to current signals, eliminating the problems inherent in RTD signal transmission via lead resistance.
