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.
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
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
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
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
