Stacktach Single Input Industrial Tachometers AI-Tek is pleased to introduce a new line of tachometers to meet today's requirements for compact packaging. Using the same highly reliant and quality design customers have come to depend on, AI-Tek now makes tachometers available in a .9"(22.5mm) DIN rail mount package. Easily programmed through a hand-held pendant, the STACKTACH's Analog Output can be set for 0-20 or 4-20 mA range for the precise scale you need. The 6 Amp, 300 Vac, C-form relay can be set for the exact speed and hysteresis required for your application. Tach-Pak 1 Digital Process Speed Switch The Tach-Pak 1 computing speed switch is a single channel instrument. It measures input frequency and converts the resulting quantities to relay closure. The microcomputer-based Tach-Pak 1 speed switch uses adaptive period averaging which permits a combination of fast response and high accuracy not available in other industrial speed instruments. The instrument functions can easily be programmed in the field or altered at any time using a unique internal switch design. Typically, a Tach-Pak 1 speed switch is used with magnetic sensors as a signal source. However, it may receive a sine wave or TTL signal from any frequency source. The resulting speed is used for alarm switching. It is superior in applications requiring fast update times and high accuracy for equipment protection. Tach-Pak 3 Digital Process Tachometers The Tach-Pak 3 computing tachometers are single channel instruments. They measure input frequency and convert the resulting quantities to a meter output, an analog output and four relays. The microcomputer-based Tach-Pak 3 tachometers use adaptive period averaging which permits a combination of fast response and high accuracy not available in other industrial speed instruments. The instruments' functions can easily be programmed in the field or altered at any time using a unique internal switch design. Typically, Tach-Pak 3 tachometers are used with magnetic sensors as a signal source. However, they may receive a sine wave or TTL signal from any frequency source. The resulting speed is used for meter output, analog output or alarms. These tachometers are superior in applications requiring fast update times and high accuracy. Tachtrol 3 Dual Input Digital Tachometers The Ai-Tek Tachtrol 3 computing tachometers are single or dual channel instruments. They measure input frequencies and display the resulting quantities in RPM, FPM, % Draw or other rates. Measurement using the period mode (time per event) permits a combination of fast response and high accuracy not available in other industrial speed instruments. A unique method of setting conversion factors and instrument functions permits them to be easily configured or altered anytime during the instruments' life. |
