Timer Boards The low cost Timer Boards control air pulsing of dust collectors. Dwyer's products have modular design. Some are solely for low voltage applications while others have multiple channels. For added safety, the control circuitry includes isolated control inputs from the line voltage. View More

Panel Meters/Indicators Panel Meters and Indicators are for displaying inputs from transmitters and sensors. Totalizing, contact outputs, and retransmission models. There are different types of mounts. View More

Process Alarm Switch Modules Process Alarm switches have selectable fields, by user. Dwyer's products can operate independently or be connected to operate as a DPDT output. All selections are made through easily accessible switches without the need to open the product. The products can be mounted on a Din Rail. View More

Signal Conditioning Modules Signal Conditioning Modules convert process signals. Dwyer's products have easy installation in which some products are transmitters and others are converters/isolators. Some products are low cost and some are specifically for low voltage units. View More

Relays From hockey puck solid state relays to intrinsically safe relays to electromechanical relays to power relays and Ice Cube relays, each relay can handle different amounts of amps. View More

Current Transformers / Switches Current Transformers and switches have either solid or split cores as well as relay outputs, LED confirmation, and an adjustable set point. Some models feature an LED for visual confirmation that current is flowing through the device. View More

SSR Monitors SSR Monitors allow easy control of resistance and some inductive loads. Dwyer's monitors protect systems and are compact. Protect your system today. View More

Indicating Annunciators Indicating Annunciators provide visible and audible alarms, relay outputs, and integral power supply. Applications include water and wastewater panels, tank level monitoring, and temperature monitoring process. Variety of Applications. View More

Intrinsically Safe Barriers Intrinsically Safe Barriers can be used to communicate with and provide isolations for certain transmitters approved for use in hazardous areas. Dwyer's barriers limit the amount of energy allowed to pass into the hazardous area, which inhibit ignition in flammable atmospheres. View More

Motion/Safety Switches Motion/Safety Switches are sensors with an electrical contact output for rotational speed, cable pull, and belt alignment. View More

Particulate (Dust or Broken Bag) Transmitters Particulate (Dust or Broken Bag) Transmitters are sensors with an electrical transmission output for remote indication of particle concentration in air flows. The particle transmitters have applications in bin vent monitoring, cyclones, filter leak, baghouses, and emissions monitoring. View More

Particulate (Dust or Broken Bag) Sensors Particulate (Dust or Broken Bag) Sensors are sensors with an electrical contact output for particle concentration in air flows. The applications include baghouses, cartridge filters, and bin vents. All models are durable and reliable. View More

Timers This category includes timers, counters, and tachometer. Some products are digital timers, compact, and have audible alarms. View More

Vibration Control Vibration Control products detect vibration and monitors the vibration. No software required for vibration switch and transmitter. Applications include motors, pumps, fans, engines, and more. View More

Enclosures Weatherproof enclosures for mounting panel meters, indicators, and controllers. Control programming buttons are easily accessible by just opening the front cover. Protects controls from dirt, dust, oil and water. View More

Signal Converter Signal Converter is a low cost device in a compact size with no external power that converts serial communications signals to a signal that is read by a computer. View More

Power Supplies and Transformers Power supplies and transformers are used to power instrumentation. Applications include BAS and HVAC. Cost efficient. View More

Control Enclosures From carbon steel to stainless steel, these enclosures can be wall mounted and are UL Approved. Perfect accessories for a variety of instrumentation. View More

Process Controllers Process Controllers monitor and control temperature or process applications. Control methods include ON/OFF, PID, fuzzy logic, self-tune, and manual tune. Self-Tune PID and different mounting options. The alarm outputs can be configured from different preprogrammed settings. View More

Questions

Question

What restrictions, if any, are imposed for the Magnehelic® and Photohelic® gages in vacuum service?

Answer

In applications involving higher vacuums than 20" Hg, leakage due to gage housing porosity becomes the limiting factor.

Question

What is the proper way to wrap the wire around the Current Transformer #CCT40-200?

Answer

If the current running through your wire is high enough to be detected by the model CCT you have, then you can simply single wrap it as you have shown in the attached PDF you provided. However, if the current is too low to be detected, then you would want to wrap the wire around until the current is high enough to be detected. Here is a link to the service manual for our Series SCT Current Transformer that explains this concept better, Series SCT Instruction Manual. See Figure 4.

Question

Is there a limit to the length of tubing used on the DCP100A pressure Module?

Answer

There is no limit to the length of tubing you connect to the DCP100A pressure module. It can be as long or as short as you need for your application. However, please note, that the longer you make the tubing, the longer the response time of the DCP100A will be.

Question

Question 1. What is the input impedance of the SPPM meter with voltage input? I'm replacing an old analog meter with a 0-100 uA movement with a more reliable digital panel meter. Question 2. The analog meter I want to replace has a two-range non-linear vibration scale 0-4 Grms and 1-10 Grms. Is it possible to create non-linear calibration curves for the SPPM?

Answer

The SPPM with the voltage input has a 10MΩ input impedance. Also, a non-linear calibration curve can be created by merely using the software in the SPPM. One can use the sensor linearization and use up to 20 calibration points and even have your results converted into a .csv file.
