Introduction
Accurate speed information is required
for the governor, over-speed protection
and other subsystems (such as Lambda
control, anti-knock system etc.). In a
modern setup, system integrators
therefore have to mount up to five
speed sensors to the engine all with
their
individual
requirements
for
placement, orientation and wiring.
Additionally, the different sensor types
have to be kept in stock as spare parts.
The JAQUET Speed Package 2 helps to
avoid this unfavourable situation. For
this task, JAQUET AG – a sensor
specialist manufacturing more than one
million sensors per year for engines and
turbochargers – offers a set of reliable
speed sensors together with the signal
repeater SR103. With this simple
solution the speed information can be
delivered to up to three independent
applications. Output drivers are able to
cope with the input requirements of
virtually all subsystems in use today.
The GreenLine sensor family is a line of more than 50 speed sensors. Sensors
are available with variable reluctance (VR) or Hall technologies with cable or
connector interfaces. Sizes range from 3/8”-24 and M10X1 to ¾”-16 and
M16X1.5 and all units have sealed sensing areas to prevent liquid intrusion. Also
available are direction sensing units and hazardous location versions for both
North America (NEC, CEC) and Europe (ATEX).
With the zero-speed detection capability of Hall effect sensors as well as the GL
approval of the whole GreenLine range, these devices are best suited as reliable
and cost-effective cam and crankshaft sensors on diesel engines.
The T400 range of tachometers allows
monitoring of rotational engine speed.
Should
a
predefined
over-speed
condition occur, the system will trigger
a relay to allow a controlled shutdown.
Additionally, it is possible to output a
proportional analogue value to be used
for indicating instruments or governor
systems. There is also an optional fivedigit display to show the engine speed
in machine values.
