Description

Senzor

The Signet 2610 RDO® Pro is a rugged, reliable sensor designed to deliver accurate dissolved oxygen (DO) data across a wide measuring range while reducing maintenance costs. It features the latest optical technology for DO measurement and eliminates the replacement of membrane and reference solutions.

The Signet 2610 optical sensor cap is calibrated at the factory and requires no field calibration. The optical measurement technology resists abrasion and bleaching allowing for a long life in many harsh applications. The DO sensor has a built in Modbus RS485 and 4 to 20 mA current loop outputs for ease of interface to existing control systems. Additional features include a 10 m (32.8 ft) cable with stripped and tinned ends as well as a titanium thermistor for improved compatibility in salt water applications.


Dissolved Oxygen:
  • No membranes or filling solutions
  • Optical DO measurement no flow requirements
  • Rugged construction
  • Calibration built into the measurement cap 2% of range 0 to 20 mg/l
  • One year measurement cap life
  • Flexible communications, 4 to 20 mA or Modbus (RS485)
  • Measurement Range: 0 to 20 mg/L

 

The 9900 Transmitter

Fot at-a-glance visibility, the 9900 Transmitter features a large auto-sensing backlit display, "dial-type" bar graph and relay and warning LEDs. The intuitive menu system is consistent with processPro and ProPoint transmitters, assuring you of a quicker and easier installation. The optional Relay, Direct Conducttivity/Resistivity, H COMM and Batch plug-in modules offers ease of use. The PC COMM configuration tool allows you to easely set-up, review, save and load all modifiable parameters. The unit can be used with default valves for quick and easy programming or can be customised with labelling, ajustable minimum and maximum dial settings, and unit and decimal measurement choices. The versatile device also allows third-party 4 to 20 mA signals to be used as an input (optional 8058 module required).

The 9900 Transmitter, a member of Signet's line of SmartPro  instruments, provides a single-channel interface for all Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, Dissolved Oxygen, Turbidity, Batch and other applications.

The 9900 is available in Panel Mount. And  runs on 10.8 to 35.2 VDC power (24 VDC nominal), and can power certain sensors on loop power.

Two dry-contact relays

In addition to the standard programmable Open Collector output in the base unit, the Panel Mount version of the 9900 has a slot for an optional Relay Module, which adds two programmable dry-contact relays. The Open Collector output in the base unit uses the Relay.

Dry-contact relays are electromechanical switches with a moving contact armature.

They are suitable for many general-purpose applications, AC or DC, including AC loads up to 250 V. Install RC Filter Kits, 3-8050.396, on relays used to switch motor or inductive loads.

 ● Two (2) SPDT dry-contact relay (DCR) inputs

 ● User programmable

 ● 250 V, 5 A maximum resistive loading (AC).

 ● Can switch line voltage (typically 120 to 240 VAC)

 ● Can switch DC voltage (< 30 VDC @ 5A)

 4 to 20 mA Output Module adds an additional 4 to 20 mA loop output to a Signet 9900 Transmitter

 ● 4 to 20 mA Output Module can be powered using Loop Power or DC Power in the 9900 base unit.

 ● Independent settings for the loop currents of the Output Module and 9900 base unit (Error, Loop Adjustments, etc.).
