477AV - Dwyer Instruments Inc.
Measures Pressure, Flow and Velocity; ±0.5% Accuracy. The SERIES 477AV Handheld Digital Manometer is now available with pressure, flow, and velocity measurements along with a number of other convenient features. The built-in air velocity and flow calculations provide accuracy and conserve time and error associated with manual calculations. Also featured on this unit are adjustable zero and span values for calibrating in the field, as well as a damping feature to compensate for the fluctuating of readings.
-
SERIES TTMP - Dwyer Instruments Inc.
THE SERIES TTMP PVC ELECTRONIC TOTALIZING METERS offer batch and cumulative flow totals in a PVC construction for 1/2" to 4" pipe sizes with spigot, NPT or flange connections.
-
1620 - Dwyer Instruments Inc.
Our old faithful switch design is still best where highest precision combined with diaphragm sealed leak proof construction and mounting simplicity are required. Model 1626 and 1627 differential pressure switches are identical in design and construction except that Model 1626 has a single electric switch and Model 1627 has dual electric switches.
-
647 - Dwyer Instruments Inc.
Monitor differential pressure in air/liquid flow systems, HVAC automation, pneumatic systems and process control with the Series 647 Wet/Wet Differential Pressure Transmitter. Units are temperature compensated and provide a 4 to 20 mA output signal which can be interfaced with chart recorders, data loggers and computerized monitoring and control systems.
-
MVA - Dwyer Instruments Inc.
The Series MVA Mini-Vane Thermo-Anemometer has the ability, depending on the model, to measure air velocity, volume flow, temperature, relative humidity, and barometric pressure. With its 1.18? diameter (30 mm) vane, the Series MVA is ideal for spot measurements at air outlets. The MVA- 02 is capable of detecting air flows up to 4921 ft/min (25 m/s) and temperatures up to 140°F (60°C).
-
668 - Dwyer Instruments Inc.
Our low cost Series 668 Differential Pressure Transmitter is capable of measuring low pressures with a ±1% accuracy - ideally suited for proper building pressurization and air flow control. Transmitters can withstand up to 10 psig overpressure with no damage to the unit. Variable capacitance sensor design provides excellent sensitivity and long-term stability.
-
Series SCC - Dwyer Instruments Inc.
The Series SCC Signal Conditioners provide maximum accuracy with minimal cost. Built-in microprocessor digitally scales, amplifies, linearizes and isolates thermocouple, RTD, current, voltage, frequency or potentiometer analog input signals. Units offer 16-bit input resolution with 0.05% full scale accuracy. Eliminate ground loops with 1500 VAC isolation. Two LEDs, one red and one green, located on the front face of the enclosure provide visual indication of operation. Additional features include short circuit, reverse power protection, digital calibration and cold junction compensation.
-
1500 - Dwyer Instruments Inc.
The Series 1500 Temperature Controller is a reliable, accurate and fully programmable temperature control or alarm in an economical 1/16 DIN case. Microprocessor based, all control functions are easily programmed from the waterproof, corrosion resistant front panel.
-
TSX - Dwyer Instruments Inc.
The microprocessor based Series TSX offers a low cost solution for cooling applications. Units are designed to accept up to two temperature probes selectable between PTC or NTC thermistor input.
-
1300 - Dwyer Instruments Inc.
The Series 1300 Smart Indicators/Transmitters are extremely versatile digital process controls, ideal for use with Dwyer pressure, temperature and flow sensors. Microprocessor based, all models are fully programmable and accept common thermocouple, RTD, current or voltage inputs.
-
APS - Dwyer Instruments Inc.
Miniature Series APS/AVS Adjustable Switches offer reliable switching for pressure/vacuum alarm, shutdown or control. The units are readily adjustable throughout their range using the locking adjusting ring and indicating pointer.
-
Series 634ES - Dwyer Instruments Inc.
Series 634ES Transmitters sense a single pressure for air, compatible gas or liquid and provide 4-20 mA output signal. Positive pressure can be measured within an accuracy of ±0.5% of span. The Series 634ES uses an isolated piezoresistive pressure sensor to produce a resistance change across a wheatstone bridge.
-
AD - Dwyer Instruments Inc.
Air/Duct Temperature Sensors are available in precision platinum, nickel, or balco RTDs and interchangeable NTC thermistors. Sensors are constructed with a hermetically sealed 304 SS sheath and are unaffected by high humidity, contamination, thermal shock or vibration
-
400 - Dwyer Instruments Inc.
Measure both pressure and air velocityRead the red figures directly in feet per minute of velocity - from 400 to 10,000 fpm No conversion tables needed for air at standard conditions. Read the black figures in inches of water column air pressure - from 0 to 10" w.c.
-
APM - Dwyer Instruments Inc.
The Series APM has a unique, rugged, NEMA 4X front panel design that makes it nearly impenetrable in typical applications. The weatherproof, UV resistant, large, dual line display allows for more information making it easier to read and even simpler to program. The intensity of the display can be adjusted allowing this meter to be utilized in dark rooms as well as outdoors, due to its sunlight readable display.
