C118.3BS
same as C118.2BS, meter equipped with RS232  interface.

C118.2BP
the appropriate kit for difficult application environments, as typical for the wet section of a paper machine, outdoor measurements for automotive tests. Includes meter with manual sensitivity preset, optosensor with increased light intensity and a 5 meter tightly attached cable.

C118.3BP
same as C118.2BP, meter equipped with RS232  interface.

C118.4
Meter additionally equipped with extra input to sensor controlled start/stop or length totalizing. Successfully used for instance, to determine the felt length in a paper machine.
Accessories to be specified separately.

Outstanding Features

Ease of use, failsafe handling, fast marking of the target. The automatic signal conditioning balances distance variations, counters noise by stains. A paint mark or other source of reflection on the target is adequate, also a blade, or a nut / cam on a shaft.

Sensors to directly plug-in or via flexible extension cable.

Range up to 1 million RPM and more (0...100 kHz).

Accuracy ± 0.05 % ± 1 in LSD.

6digit LCD display, with selection to ../sec, ../min, ../h, or to controlled event totalizing.
Decimals fixed or programmable.
MAX, MIN and average memory, for a controlled period.

Incorporated data computer, on call for derived quantities, such as circumferential speed, gear reduced speed, flowrate.
6 digit factor for multiplication or division.

Analog output 0 ...4 volts, with programmable span.

Programmable input frequency divider to reduce to 1 pulse per revolution, thereby compensating an irregular input sequence

TTL pulse output (reduced to 1 pulse per rev).

Event totalising function with programmable scaling factor. Controllable start and stop of period by key.

Data interface RS 232 (option) providing all measurements, on demand or continuously (programmable).

Supply by inserted batteries or rechargeable cells (optional), or  from AC-mains (extra accessory with plug-in cable).

Programmable automatic shut-off when idling.

Sensors for special requirements Besides of the optosensor, which is part of the standard equipments, there are others, useful for specific applications. For more details, see section Sensors.

• Optosensor series A1S...
  Series A1S30 and A1S36 are available with a reduced shaft length of 35 mm (instead of standard 95mm). When space is at a premium, there is version A1S36WP35, with angled tight attachment of its cable.
  Our Laser type sensor A1S37P detects a target from a distance of over 2 meters. Or, through a narrow opening. Requires marking with U1A006 reflection tape.

• Differential Hall-Effect series A5S..
  Speed of rotating steel profiles (gear wheels, slots, etc.) under difficult ambient conditions: under oil or water, temperature -40 °C...+125 °C, extreme illumination. From zero up to very high speed.
  
  

• Magnetic pick-up series A2S...
  Detect an alternating magnetic field, as around an electric motor, transformer or ignition coil, or by a rotating magnet.
  
  

• Wheel pulse transmitters
  Running on a web or roll surface, to measure speed or totalizing length. Available with two wheels (series A1L..).
  Speed range up to 3000 m/min.

Useful Accessories

• Alternatives to supply the C118 meter
  Besides of the standard batteries, a set of rechargeable cells is available (No. IECR6) with charger (U1H009).
  For measurements of long duration, the supply adapter U1H008 can be used. It connects to the AC mains 100...250 volts). Its output cable connects to a jack on the C118 (all versions).
  
  

• Connecting the C118 outputs
  Ready made plug-in cable fitting either the analog output or the pulse output, with a BNC connector at the other end. Part No. U1H012.
  Alternatively, a set of 3 single connectors, part No. MST2-3er.
  
  

• Connecting the C118 signal input
  All our sensors fit the C118 signal input, for direct plug-in or via the extension cable. The SAK-2m is part of the standard kit, increased length is available, also versions to connect our specific sensor models.
  To connect other signal sources, screened cables are available ready to plug-in, with open ends or BNC connector.
