The TACHTROL20 Rate Meter, Model T77250-10, provides the versatility and flexibility needed to
accommodate virtually any rate measuring application. The meter has the ability to scale for direct
readout in terms of the units being measured. Whether a machine produces bottles, cloth, wire, or
beverage mix, operation is enhanced when the rate readout is expressed directly in bottles/min.,
feet/min., gallons/min., or whatever units are needed in plant applications.
The TACHTROL20 can accommodate magnetic pickups, logic sensors, and NPN open collector sensors.
The pulses are received and scaled, so the desired display can be achieved. The meter is programmed
through both the front panel buttons and DIP switches. Once the programming is complete, the front
panel buttons can be disabled by a DIP switch setting.
The meter has been specifically designed for harsh industrial environments. With a NEMA 4X/IP65 sealed
bezel and extensive testing to meet CE requirements, the meter provides a tough, yet reliable application
solution.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the literature or on equipment
must be observed to ensure personal safety and to prevent damage to either the instrument or equipment
connected to it. If equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
