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.
Product contact materials:- Pt100 and Prism Holder in 316 AISI stainless
steel (Hastelloy, Incoalloy on request).- O-rings and Seals in Kalrez 6230 + Viton or
EPDM (Silicone, Kalrez 6375 or 6380 on
request).- Measurement prism in Synthetic Sapphire
or Optical Glass (Crown N-K5, BariumLight Flint BaLF4, Borosilicate Crown N-BK10).
