Strain,Gauge,Loadcell,Panel,Meter,Eagle ControlsGeneral Introduction

A competitively priced, fully programmable Strain Gauge/Loadcell panel meter suitable for Loadcells with a typical sensitivity of 2mv/V and for high sensitivity applications. It features a fully scaleable 5 digit bi-colour LED display across the range -9999 to +99999. 4 alarm output options are fitted as standard where the display changes colour in the alarm condition if programmed to do so. Analogue output via an external isolator is an option (consult sales office) and serial communications RS-485 input and output is fitted as standard.

For high accuracy (6 wire) and Intrinsically Safe applications use a BASEEFA Certified isolator, consult sales office.

Display Colour selection
The display may be programmed to be

  • RED (normal) to GREEN (in alarm)
  • GREEN (normal) to RED (in alarm)

Standard features

  • Display range -9999 to +99999 scaleable
  • Display colour change in alarm state
  • Span & Tare
  • Input +/- 50mV for maximum reading of -9999 to +99999
  • Serial communications RS-485 (programmable) send, broad cast, receive. 4 programmable alarm outputs
  • Programmable decimal point position, Programmable display blanking, Programmable last digit filter 1, 5, 10, 25, 50 Excitation for field transmitters 15vdc @ 35mA IP65 / NEMA 4 front panel protection CE approved, UL pending

4 Alarm Outputs
4 alarm outputs are available via N/O 3 A relays. The alarms are fully scaleable and independent of one another and may be set for HI or LO trip. The alarms can be programmed to energise or de-energise in the alarm state, open / close or latch and have independent variable hysteresis, time delay trip response adjustable 0-250 seconds. In the alarm state the display will change colour if programmed to do so.

Serial Input / Output (fitted as standard)
Up to 31 units may be multi-dropped. The displayed value can be uploaded or downloaded from a PC via an RS-485 port. One unit can also be programmed as a 'master' with the remaining multi-dropped units acting as OEslavesą.

Analogue Output Option
Isolated 4-20mA or 0-10V, for an assigned zero and span can be supplied as an output option.
