Electro-Sensors SG1000A is a 4-20 mA output slide gate sensor that provides independent and accurate feedback of gate or valve position to an external device such as a PLC or optional process meter. The display decodes the signal from the SG1000A and shows the percentage open between zero (fully closed) and 100 (fully open), allowing the gate to be accurately positioned when regulating the flow of a product or blending more than one raw material. The SG1000A mounts directly to the end of the sli... more
The FB420 Shaft Speed Switch / Shaft Speed Sensor with SPDT Relay works with Electro-Sensors magnetic pulser discs and wraps. It provides a 4-20mA signal directly proportional to the rotational speed of a monitored shaft and has a 4 digit LCD display capable of displaying from 0.000 to 9,999 rpm or from 4 to 20 mA, the display is also used for calibration and troubleshooting. The FB420 has one relay that can be programmed for failsafe over speed alarm or failsafe under speed alarm.

The patented ST420-LT and ST420-DI are 2-wire, loop-powered, 4-20mA analog output shaft speed sensors. They detect passing magnets of a shaft-mounted pulser disc or wrap and output a smooth, continuous 4-20 mA analog signal in direct proportion to shaft rotation speed. The ST420-LT and ST420-DI have integral conduit attachments, are NEMA 4X, IP65 and Dust Ignition-proof for Class II, Div I (E, F, G) hazardous locations.
All models have rugged stainless steel M18x1 housings for harsh enviro... more
Electro-Sensors is excited to announce the new PM500, an economical process meter that can run as a standalone ratemeter or can be configured to run as a complete control and display system. The PM500 is fully programmable and has two 4-20 mA sensor inputs that can be scaled to any user-selected units. Although there are many different types of sensor inputs, the most common are temperature, speed, and position. The PM500 can be programmed to display two different processes because the inputs ar... more
The TR400 is a full logic control process ratemeter that can display any production rate or time-in-process easily and accurately. The ability to accurately detect and convert 0.01 to 4,000 Hz signal input makes the TR400 an inexpensive solution to many industrial applications. With the addition of optional relay outputs and/or 4-20 mA analog output, the TR400 becomes a complete process control and display system. The optional relay outputs can be programmed for under-speed or over-speed, and in... more
The SG1000A slide gate position sensor is a complete monitoring system housed in a compact and rugged explosion proof enclosure. It provides independent, accurate feedback of slide gate position to a controller (PLC) or Electro-Sensors optional remote display.
The SG1000A mounts directly to the end of the slide gate drive shaft and is easily calibrated with a single push button for setting the fully open and fully closed limit points of the gate. A second directional switch (clockwis... more
