BENEFITS
Fast, flexible and easy handling
Easy adjustment to the application
due to mobile use
Sensors to directly plug-in or
via flexible extension cable
Tachometer C118 + cable SAK-2m + sensor A1S30P 95
Ideally suited to quickly perform speed checks
The BRAUN C118 hand-held tachometer is used for a quickly performed speed check, and
for longer term studies as well. For inspection and maintenance, to optimize and adjust
drives, at rolls, spindles, and other objects. At paper, textile and foil applications.
The C118 tachometer can handle up to 1 million RPM (0 Hz…100 kHz). Its 6 digit LCD
display is reading speed by selectable units /min or /sec or other units.
The operation mode can be selected by a push-button between straight tachometer
function and use of incorporated programmable computing facilities.
Its signal input is universally designed and fits for BRAUN sensors and wheel pulse
transmitters.
The analog output 0…4 V is short circuit protected with a source impedance of 100 ohms.
Its TTL pulse output (5 V) is square wave shaped, with its sequence repeating the input.
The C118 tachometer is fast and easy to handle and due to its mobile use very easy to
adjust to the required application. All sensors can be connected directly via plug-in or via
flexible extension cable.
