Accurate Carbon Potential Measurement for Heat Treatment Applications
The Novatech 1734 controller with a variety of gases including
- Nitrogen / Methanol
Using the Novatech 1734 is easy and convenient
- Simply enter the gas component data via the analyser’s keypad.
- The 1734 is self-calibrating, performing a calibration cycle for all inputs, every minute.
- Output to a computer or printer is provided via RS233 or RS485 ports, facilitating diagnostics of the analyser, probe or combustion appliance.
The Novatech 1734 Controller readily adapts to your process control system
The 1734 Controller has two 4-20mA linearised outputs to operate with remote controllers and/or indicators.
The instrument’s common alarm relay can activate remote process alarm devices.
The separate, ‘probe not ready’ alarm relay prevents erroneous operation.
During auto-purge cycles, the analyser output is frozen, and the purge relay is activated.
An alarm horn driver relay is provided.
Novatech’s dual sensor redundancy feature prevents costly shutdowns if a probe failure occurs
The Novatech 1734 Carbon Controller accepts inputs from two sensors, averaging the two readings, or providing separate 4-20mA outputs for each sensor. In case of either one of the sensors failing, the analyser warns the operator and locks onto the remaining sensor so that the process can continue to operate.
The Novatech 1734 tells you what’s happening
Plant operators are alerted to failure of the probe by a plain English message on the analyser LCD display. There are 20 probe and analyser alarms, plus 4 process alarms. The upper line display indicates carbon potential
Note: gases allowed for are propane, methane, nitrogen/methanol mix.
The lower line display can indicate any one of the following:
- Oxygen %
- Carbon set point
- Probe impedance
- Probe EMF
- Probe temperature
- Auxiliary thermocouple temperature
- Ambient temperature
- Run hours
The Novatech 1734 can control your furnace atmosphere
The Novatech 1734 has a built-in carbon controller thus providing furnace atmosphere control. Features include:
- ON/OFF control
- Proportional ON/OFF control
- Proportional 4-20 mA control signal
- Proportional Up/Down control
