2. INSTALLING THE CS OEM SENSOR HEAD SERIES
Installation must be performed by an operator qualified to
the use of voltage devices. LaserPoint is in no way liable for
any damage resulting from misuse, careless or use above
rated limits for the instrument.
2.1 -General
This series includes
compact, conduction or water cooled
heads: the setup is made by sensor disk,
housing and a connecting device
(LaserPoint’s Intelligente Identification
System-IIS, BNC connector or Pigtail output).
The head has been previously mounted and tested in
house, so no additional work has to be done except
connecting to a conditioning electronics and
calibrate.
Output Signal Voltages depend on the
applied amount of power/energy and are
expressed as mV per incident W (mV/W). The amount of successive amplification thus depends on
the overall measurement range (Min to Max value). A safe minimum measurable value, to avoid
influence of noise, has to be considered as at least 4 times the value of NEP (Noise Equivalent
Power) . Please refer to the head specs table at the end of this catalog to identify the correct value of
NEP.
As a safety rule, never let the sensor disc area face power/ energy densities (originated by a too
small size beam or hot spots) that exceed the values specified for the absorbing coating . If the
absorber is damaged, measurements may be affected and a substitution of the sensor may be
necessary (refer to Section 4 for individual threshold of each sensor).
2.2-Output Signal Condictioning
External connection options include Laser Point’s IIS
(Intelligent Identification System) on DB15
connector, BNC, 4 wire pigtail.
2.2.1-The DB15 Connector –
Heads with DB-15 male connectors are only provided for use with
LaserPoints readouts like the LPM, PLUS or PC-Link, either in their
laboratory or OEM versions .
LaserPoint’s Intelligent Identification System (IIS) is composed by the
DB15 connector, EEPROM and cable between the CS head and
electronics. Within the EEPROM all relevant parameter of detectors are
stored: each detector automatically identifies itself to the electronics and
supplies the stored data. The monitor is then in condition to know the
head sensitivity, the correction factors for various wavelengths or the
detector intrinsic response times, necessary to provide suitable speed-up of readings.
2.2.2
-
BNC connectors
– They give total plug/un-plug ease and high EMI noise shielding.
Connector polarities are (+)at the central pin and (-) on the outer body. Standard BNC Connectors
are panel female, 50 Ω
2.2.3-Pigtail Output
:
- Heads have, as standard, a 1.5m cable terminating with bare wires for
custom links to the machine. Custom lengths can be provided on request up to 5m.
1-For any connection: the exit cable is delivered with a Yellow (+) and Brown (-), low impedance
leads. If an optional thermistor KTY 11-6 (2K
at 25°C) is internally mounted for temperature
monitoring, two extra White and Green wires are available.
