Product Categories | Dwyer Instruments

Pressure: Known for quality, reliability and accuracy, Dwyer designs and manufactures a full-line of Controllers, Data Loggers, Gages, Manometers, Monitors, Remote Displays, Switches, Transmitters, and Accessories to measure, monitor and control pressure, air velocity, flow, fan pressure, duct, and more.

Air Velocity: Dwyer offers Wind Meters that have the option of Pocket Wind Meters and handheld meters. There are also Wind Speed Indicators and Vaneometers that are designed to simplify the measurement of low air velocities. Air Velocity Transmitters are sold in this category which are ideal for monitoring air flow.

Flow: Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston.

Level: Level includes Bin Vibrators - ideal in high vibration. Pump Controllers monitor pump levels and leaks. Level Indicators are customizable to fit any application. Level Switches come in diaphragm, tuning fork, and more. Level Transmitters are capacitive, float, submersible, or ultrasonic. Water Leak Detectors monitor water levels.

Temperature: Process Controllers and Din Rail Temperature Controllers monitor and control temperature, defrost, and fan cycles. Dwyer offer selections of Transmitters, Thermostats, Digital Panel Mount, Limit Switches, Mechanical Switches and Thermometers available in dial, spirit filled, or digital. Indicators are available with digital LCD displays.

Process Control: Dwyer sells Alarm Switch Modules, Chart Recorders, Current and Particulate Transformers/Switches, Data Loggers, Fan Speed Controllers, Intrinsically Safe Barriers, Indicating Annunciators, Motion/Safety Switches, Power Supplies and Transformers, Relays, Signal Conditioners/Converters, SSR Monitors, and more.

Data Loggers & Recorders: Data Loggers available are Button, High Temperature, Humidity, LCD, Portable, Pressure, Process, Submersible, Temperature, USB, Wireless, and Water Level Data Loggers; Software for communicating with these Data Loggers. Some data loggers are compact and stainless steel. These Data Loggers monitor various applications.

Test, Adjust, & Balance: Test Equipment has instruments for calibration, measurement, test of Air Velocity and Flow, and monitor Back Flow, Carbon Monoxide, and Combustion. Distance, Electrical Control Signals, Electricity, Gas Detection/Analysis, Ground and Continuity meters are available. HVAC Balancing, Humidity, Light, and many more are available.

Valves: Valves include Ball, Butterfly, Check, Globe, Needle, and Solenoid Valves. Actuators come in pneumatic and electric, Air Filters have different fittings and port sizes, Connectors eliminate need of welding, Electro-Pneumatic Contollers, Current/Pressure Transducers, Positioners, Position Indicators are linear or rotary operation, and Volume Boosters.
