The durable NorthStar SLIM Tach® SL56 operates with unequalled resistance to grease, oil, salt water, dirt, fibers, and dust. Its hardened, encapsulated electronics make it immune to contamination, heavy machine vibration, and accidental impact, decreasing downtime. Hard, anodized aluminum of aircraft quality makes the SL56 the toughest, yet lightest, C-Face encoder (read more)

Servo-Tek low-ripple tach generators satisfy the need for a low-cost, very low-ripple tachometer. In addition to being the first economical low-ripple units of their type, Series F and H tachs incorporate all the desirable features of the Servo-Tek generator line-temperature compensation, long brush life, excellent linearity, etc. (read more)

Avtron M6 Encoders are hollow shaft mounted, and fit up to a 2 3/8" shaft directly. M6 encoders are designed for use in explosive environments like volatile vapor, flammable dust, or gases. The M6's are extremely durable and resist water, oil, moisture, and dirt. M6's are also available in solid shaft coupled models. (read more)

Avtron Model K661 Brushless Tach replaces analog tachogenerators like the GE BC-42 and BC-46 or the Reliance Electric RE-210. Upgrade them without the need to change your drives to accept frequency inputs. Analog tachs are DC Generators that put out voltage signals at 50, 100, or 200 VDC per 1000 RPM. If you are in this situation, Avtron has a solution. You can install an Avtron Encoder on the... (read more)

Lightweight, Premix Combustion, Variable Speed Blowers Meet the Need For Lower Emission Gas Burner Systems (read more)

SmartFan^® Cirrus-6 offers a very cost effective means to control and monitor fan speed in electronic systems being managed by an I2C interface. The simple to use interface allows the user to control fan speed to regulate temperature, reduce acoustical noise and extend fan service life. Undetected fan failure in an electronic system can be catastrophic. To avoid this, th... (read more)

The SmartFan Vortex is an I2C fan speed control and alarm designed for 12 VDC fans. Vortex can control and monitor tach pulses from up to four fans. The controller accepts fan speed commands (including on/off) and provides individual pass/fail fan status via an I2C interface. Fan speed can also be based on temperature. The I2C interface also provides temperature readings from an on-board thermi... (read more)

Control Resources Introduces New Fan Speed Alarm

Control Resources' SmartFan TachScan-9 digital fan speed alarm monitors tach pulses from up to nine DC fans or blowers and provides OR'd pass/fail signals. (read more)
