Electro-Sensors, Inc. announces the SG1000E Position Monitor, designed for measuring linear and rotary movement in clam shell bucket applications. The E-model is the newest addition to the company’s line of SG-Series Position Monitors, which measure rotary movement up to 6 turns as well as repetitive linear movement. With a complete monitoring system housed in a compact and rugged explosion-proof NEMA 4X enclosure, SG-Series Position Monitors provide accurate positional feedback for precise process control—even in harsh industrial applications. SG-Series Position Monitors work with electrically, pneumatically, hydraulically or manually driven shafts.

Electro-Sensors, Inc. announces that the TR400 ratemeter—which displays an automated system’s production rate or time in process with high accuracy—now features a system slowdown test to simply verify relay setpoints and operation. The TR400’s system slowdown test allows users to periodically test setpoints while the system is functioning normally, with no system recalibration required after testing is complete. With the system slowdown test, there is no risk of losing setpoint values, saving significant costs and time.

Electro-Sensors, Inc. announces the ST420, a loop-powered, stainless steel analog shaft tachometer. The ST420 requires no user calibration, providing a dependable shaft speed monitoring solution right out of the box. The rugged, compact ST420—only 18mm in diameter—reliably detects magnetic pulses from a rotating shaft-mounted pulser disc or wrap. Then, the ST420 uses quartz crystal-based digital processing to convert pulses to a smooth, continuous 4-20mA analog signal directly proportional to the pulse frequency. The result is a plug-and-play solution that allows users to accurately and simply monitor rotating shaft speed in industrial applications.
