Sample Draw Non-Explosion Proof

Modular design makes sensors interchangeable – SEC 3000 Toxic – SEC IREvolution PFC –SEC IREvolution HC

• Sample flow monitoring – Digital low flow alarm
• Stand-alone system or connect to SEC 3100/3120 Transmitters
• Flow housings can accommodate one sensor module
• Optional heater for sensor with close loop temperature control ensures accuracy in low temperature applications
• Power unit from 24 VDC power supply
• Closed loop pump control ensure flow rate is kept constant even with a variable load
• Two 4-20 mA outputs to monitor both pump and sensor
• Three indicator LEDs on cover: Power indication
• Pump status indication
• Sensor status indication
• Powder coated white steel construction

The SEC Sample Draw provides the ability to pull a gas sample from a remote area, confined space, chamber and measure it remotely up to 200’ distance.

The features include the following:

• Modular design of sensor allowing for easy replacement and change of sensor board or sensor module
• Two independent 4-20 mA outputs to monitor both the sensor and the pump
• Two independent data wires to be used for calibration and communication between SEC transmitters
• Can be used with the SEC 3120 Transmitters
  • The 3120 Transmitter will monitor the pump and the sensor simultaneously
  • The unit can be mounted separately from the SEC 3120 Transmitter
  • Easy flow calibration can be done by transmitter, no use of flow meter required
  • Flow rate set by ‘Cal Value’ on transmitter, pump will automatically adjust to meet flow rate
• Can be used with SEC 3100 transmitters using multiplexed data wire
• Unit will normally show sensor display unless a problem is detected with the pump
• Can use a magnet to switch from sensor display to pump display on 3100 for calibration
