DISATAC - Electronic tachometers

DISATAC is a series of rugged, noncontact electronic tachometers that monitor rotational speed in all types of highspeed turbochargers and other kinds of rotating machinery. Only high-quality materials are used in the manufacture of DISATAC tachometers to ensure optimal, reliable and long-lasting performance in harsh working environments. Except in 72H.. systems, the measurement principle is based on a magnet mounted on a rotating part inducing an alternating voltage in a DISATAC pickup placed a specific distance from the magnet (or, in 72H.. systems, another rotating part). As the...

72B DISATAC systems The rotating magnet mounted on the shaft of the turbocharger induces an alternating voltage in the pickup. The electronic unit converts the signal to a current proportional to the rotational speed. The output is able to drive one or more meters, dataloggers or recorders and a current loop, depending on the model. 72 B-series does not require external power supply. 72H DISATAC systems The pickup senses the induction from e.g. a gearwheel and the electronic unit converts the signal to a current proportional to the rotating speed. The 72H systems can also be used with 72C...

Selecting pickup and magnet There are two series of DISATAC pickups. • The 72C-series, with two types of pickup/magnet: 2-pole and 4-pole. These pickups and their corresponding magnets are for use with both the 72B-series and 72H01 DISATAC electronic units. • The 72K-series. These pickups can only be used with the 72H01 or 72H03 DISATAC electronic units. They do not require a rotating magnet, but are simply positioned next to any gear-wheel, perforated disk, shaft with bosses or equivalent. The rotating part must be of ferrous material, so that a signal is generated. The type of pickup to...

Turbocharger supplier Turbocharger type RATEAU France Gebr. SULZER Switzerland BURMEISTER & WAIN Denmark ELSINORE SHIPYARD Denmark MAN Germany (Turbochargers are delivered with pickup and magnet built in.) NAPIER England DISATAC 72B.. series and 72H01 electronic units are compatible with MAN turbochargers with built-in pickup/magnet. Output from this pickup corresponds to the output from a DISATAC 72C.. 2-pole pickup. * Discontinued. Please contact Dantec Dynamics for availability

a) Other pickup types: Please check with Dantec Dynamics before ordering. (MAN turbochargers with built-in pickup correspond to a 2-pole pickup) b) Maximum impedance of meters connected in series: 9 kQ. c) The 72H01 unit has a recorder/datalogger output of 0-100 mV DC. d) Electronic units in the standard 72B-series are powered by the energy generated by the magnetic pickup. They therefore require no external power supply. NB: Degree of protection: IP65 for all electronic units.

CONNECTION OPTIONS FOR DISATAC SYSTEMS The DISATAC 72B30 electronic unit has facilities for connecting one DISATAC meter. The DISATAC 72B50 electronic unit has a built-in pointer instrument (meter) as well as facilities for connecting one or two additional DISATAC meters. The DISATAC 72B60 electronic unit is designed for panel mounting. It has provision for connecting one, two or three DISATAC meters. The DISATAC 72B61 electronic unit is a recorder version for panel mounting, with provision for connecting one recorder and one or two DISATAC meters.

CONNECTION OPTIONS FOR DISATAC SYSTEMS The DISATAC 72B62 electronic unit is a datalogger version for panel mounting, with provision for connecting one datalogger and one or two DISATAC meters. The DISATAC 72B63 electronic unit is a meter version for panel mounting. It has provision for connecting one or two DISATAC meters and an additional recorder output with an isolated passive 2-wire transmitter (4-20 mA DC current loop). The DISATAC 72H-series electronic unit is a meter version for panel mounting. It has provision for connecting one or two DISATAC meters and an additional...
