InterfacesAnalog: 0...20mA or 4...20mA into 470
Digital: -RS422/485 for connection to Repeater, PC orAutomation
Systems.
-N1 PROFIBUS by means of 1 Module (optional)for Profibus-DP
network with DC 24V powersupply.
Inputs: N1 "Line Stop" input (HOLD).
Outputs: N1 relay output for alarm signal or control ofCleaning
System, with contact rating of DC/AC24V/500mA.
All the interfaces are optically decoupled from the power
supply(VDE0160) and completely configurable from the keypad.
Allconnections to be made by means of round 16 pin
metallicconnector.
CONSTRUCTION FEATURES
Execution: One-piece enclosure with 316 AISI stainlesssteel
cover, Thermal isolation flange inPEEK, 316 AISI stainless steel
prism
holder with 3" Tri-Clamp BS 4825 ASME-
BPE or Varivent type N connection forinstallation on process
line. Tank mountingversion (LP) features attachment with 70
mmoffset.
Measure. Section: - Measurement prism in Synthetic Sapphireor
Optical Glass (Crown N-K5, BariumLight Flint BaLF4, Borosilicate
Crown N-BK10).
- Electronically compensated LED lightsource.
- CCD sensor element.- Pt100 temperature sensor to install in
line
or internally to unit for tank applications.
The optical section of the unit is dehumidified by means of
aMolecular Sieve desiccant cartridge.
Electronic Section:- Microprocessor CPU.- Measurement readings,
program menus and
error messages presented on a 128x64 pointbacklit graphic LCD
display with LCDSaving function.
- Moulded keypad in scratchproof polyesterwith dome keys.
- Choice of 5 interface languages (English,German, French,
Italian, Spanish) for thedisplay of menus and messages.
- Temperature readings in C or F.
