DYNALCO SPD100-1

DYNALCO SPD100-1

1. Product NameDYNALCO SPD100 – 1 Signal – Powered Intrinsically Safe Digital Tachometer
2. Product DescriptionThe DYNALCO SPD100 – 1 is a solid – state digital tachometer designed primarily for precise rotational speed measurement in industrial settings. It gets both signal and power entirely from magnetic pickups, pulsers, or shaft encoders, eliminating the need for independent power supply connections, which simplifies the installation process significantly.
   Being intrinsically safe, this tachometer can be safely applied in hazardous industrial environments when paired with approved DYNALCO pickups. It boasts high immunity to electrical noise and excellent resistance to shock and vibration, adhering to MIL – STD 810C standards, allowing it to maintain stable performance in harsh indoor and outdoor working conditions.
   With a field – programmable gate time range and the ability to be field – calibrated, it can adapt to a wide range of pulse – per – second requirements from different devices. It can also be paralleled with governors and speed switches and share existing pickups or pulsers while drawing only microamperes of current. Its gasketed and spray – proof structure, along with ground – free and non – polar terminals, makes it ideal for OEM applications and ensures convenient installation and reliable operation in various industrial fields.
