Company Overview
Dwyer Instruments, founded in 1931, is headquartered in Michigan, USA, and recognized for quality instrumentation in the process and automation industry. The company offers solutions for level, flow, temperature, pressure, vibration, and emergency shutdowns in harsh environments.
Level and Flow Measurement
Dwyer produces a wide range of level sensing devices, including:
- Capacitive Level Transmitters: Reliable push-button calibration sensors for liquid and solid level control.
- Ultrasonic Level Sensors (e.g., ULSM-10): Non-contact measurement with programmable relays, suitable for tank and silo applications.
- Bulk Flow Monitors (BFM Series): Designed to detect flow or no-flow conditions in chutes and conveyors.
Speed and Vibration Monitoring
Dwyer also delivers sensing solutions for motion analysis:
- NSS Speed Switch: A non-contact magnetic speed detector used on conveyor shafts to detect slippage or stoppage and prevent equipment failure.
- Vibration Monitors: Portable instruments and accessories used in predictive maintenance to detect mechanical issues early.
Cable Pull Emergency Switches
The Model CPS cable pull switch provides critical emergency stop functionality across conveyors and belt systems:
- Constructed in a durable NEMA 6 (IP67) die-cast housing, bi-directional actuation, and manual reset flag indicator.
- Used in applications including bucket elevators, ship loading conveyors, and tripper systems to ensure immediate shutdown upon rope activation.
