Knick 830 X S1 Loop Power Supply Type Process Digital Display Meter

Product Description

Knick 830 X S1 is a loop‑powered intrinsically‑safe process indicator manufactured by Knick Germany. S1 denotes panel cut‑out mounting form. It draws power directly from 4‑20 mA / 0‑20 mA analog current loop without external auxiliary power supplyNEX Instru…. HART‑compatible, it displays process values locally within transmitter signal loops. Equipped with 4‑digit large‑size LCD plus bar‑graph indication. Four front‑panel push‑buttons allow range, engineering‑unit and alarm threshold configuration. Certified for intrinsic safety for hazardous locations. Only 0.5 V voltage drop imposes minimal load impact on signal loop, display activates at loop current as low as 0.3 mA. Exchangeable unit labels are supported; optional floating min/max outputs are available. Front face IP65 rated for cabinet panel mounting. Some variants are phased‑out. Surplus‑new and tested‑refurbished units serve as critical local‑display instruments for chemical and oil‑gas hazardous‑area sites.

3. Product Application

830 X S1 loop‑powered indicator provides local on‑site readout for 4‑20 mA transmitter loops in hazardous industrial areas. Main application fields are listed below:

1. Petrochemical & Chemical Plants: Local display for pressure, level and flow transmitters in explosive zones, no separate power wiring needed.
2. Oil‑gas Sites & Offshore Platforms: On‑site visual monitoring of temperature & pressure parameters for Zone 1 / Zone 2 hazardous locations.
3. Pharmaceutical & Fine‑chemical Facilities: Local readout unit for intrinsic‑safe signal loops inside explosion‑risk workshops.
4. Water‑treatment Facilities: Field value display for analog measurement loops in chemical wastewater explosive sections.
5. Power Generation Plants: Supplementary local indication for transmitters in hazardous auxiliary areas beside central DCS supervision.
6. Legacy‑system Maintenance & Retrofit: Replacement for failed Knick 830 series indicators, overhaul spare‑parts for explosion‑protected automation systems.
