Product
Digihelic Differential Pressure Controller
DH
-
The Series DH Digihelic Differential Pressure Controller is a 3 in 1 instrument possessing a digital display gage, control relay switches, and a transmitter with current output. Combining these 3 features allows the reduction of several instruments with one product, saving inventory, installation time and money.

Product
Temperature/Process Controller
8600
-
Series 8600 Temperature/Process Controllers set a new standard for quality, ease-of-use and value. While a high level of standard features are included, many function setup items appear in the control menu only when the function is selected, so you don't have to wade through unnecessary items

Product
Dust Collector Timer Controller
DCT1000DC
-
Simplify your on-demand cleaning requirements with the Series DCT1000DC Dust Collector Timer Controller. Relying on one timer board for on demand and continuous cleaning applications, the DCT1000DC eliminates external devices such as pressure switches, relays and timers.

Product
Molded Plastic Manometers
Mark II
-
Dwyer Mark II series molded manometers are of the inclined and inclined-vertical types. The curved inclined-vertical tube of the Model 25 gage provides higher ranges with more easily read increments at low readings.
-
Product
Explosion-Proof Differential Pressure Switch
H3
-
Explosion-proof, heavy duty, industrial unit has patented and unique new design which provides sensitivity to differential pressures as low as 10 inches of water (254 mm w.c.), yet handles total pressure of 1500 psi (103 bar). Unlike common differential pressure switches that use a piston-type motion transfer, the Series H3 utilizes a rotary motion transfer shaft that prevents a change in total pressure from causing a setpoint shift.

Product
DATA LOGGER
Dl7
-
Monitor and Record low differential pressures and temperature with the model DL7 Differential Pressure Data Logger. Unit includes an onboard thermistor for ambient temperature measurement
-
Product
Bourdon Tube Operated Pressure Switch
DA/DS
-
Customers tell us that this is the best pressure switch made. The Mercoid D Series is one of the world's broadest lines of pressure switches. Whatever your application might be, it is most probable it can be fully satisfied with a D Series pressure switch
-
Product
Push-Button Temperature Transmitter
659
-
Series 659 Push-Button Temperature Transmitters accept thermocouple (J, K, T), RTD (Pt100Ω) or thermistor input and provide a linearized 4 to 20 mA output. The transmitter is quickly ranged and calibrated by using a single on-board switch
-
Product
Flex-Tube Well-Type Manometer
1235
-
Dwyer Flex-Tube Well Type Manometers are designed to meet the need for a direct reading single column instrument providing highly accurate pressure readings; positive, negative or differential. Unlike other makes, Dwyer manometers have no hidden wells or packing glands
-
Product
Temperature Data Logger
DL001
-
Record temperature in a wide range of applications including HVAC testing and balancing, transportation, and energy management with the Model DL001 Temperature Data Logger. Temperature logger has an on-board thermistor and an external sensor channel for remote temperature measurements
-
Product
Differential Pressure Transmitter
616W
-
Positive, negative and differential pressures can be measured within a full span accuracy of ±0.25 with the Series 616W Differential Pressure Transmitter. Units are enclosed in a polycarbonate case, rated NEMA 4X (IP66) and operate by sensing the pressure of air and compatible gases then sending a standard 4-20 mA output signal.

Product
SAFE-T-GROUND - Ground Continuity Monitor / Control
TR-7
-
Model TR-7 Safe-T-Ground provides continuous monitoring of a truck's ground connection throughout loading operations. Static electricity is often brought in by tank trucks entering the loading area. The Safe-T-Ground Model TR-7 instantly stops loading operations if a tank truck loses its ground.
-
Product
Data Logger +
DL-8T
-
Monitor and record temperature in eight different locations with the Model DL-8T Temperature Logger. The DL-8T has a built-in sensor for local temperature monitoring and accepts seven external thermocouples in types J, K, T, S, or E.
-
Product
Floating Contact Null Switch
1640
-
The unique electric switch design in the 1640 is another Dwyer Instrument, Inc. innovation. The Dwyer Model 1640 Differential Pressure Switch resembles the Series 1630 switches. The Model 1640, however, is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch.
-
Product
Diaphragm Operated Dual-Action Pressure Switch
H2
-
Explosion-proof, UL & CSA Listed for Class I, Groups B, C & D and Class II, Groups E, F & G. The H2 is designed for sequencing two different actions as pressure of a liquid or gas increases or decreases. The patented design consists of two concentric pistons operated by a single diaphragm with one pressure chamber.
