Sample Draw Non-Explosion Proof
- 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
