INTELLIGENT HYDROGEN SAMPLING SYSTEM FOR NITRIDING & NITROCARBURIZING
The H2Smart™ measures hydrogen content with high accuracy in process atmospheres. It features an integrated sampling system with flow control to ensure reliable sampling and measurement. The H2Smart™ can be stand-alone or integrated into a new or existing control system.
H2Smart™ is available in 3 models:
Power requirements: | 2.5 amps max.@ 24 VDC |
Outputs: | 2 x analog, sourcing, individually isolated, |
4 -20 mA (R<500 Ohm) | |
4 x digital OUT, 24 VDC, 0.7 A max. | |
Inputs: | 1 x analog, dedicated temperature sensor (optional) |
2 x digital, 24 VDC | |
Weight: | 8.8 lb. / 4 kg |
Dimensions: | 7.5” H x 6.7” W x 5.5” D |
190 H mm x 170 mm W x 140 mm D | |
Process connection | ¼” tubing (6 mm tubing adaptor available) |
Performance | |
Accuracy: | +/- 0.5% of reading plus +/- 0.3% of full scale |
Linearity: | < 0.5% of full scale |
Repeatability: | < 0.5% of full scale |
Zero drift: | < 0.5% of full scale per month |
Sampling flow: | 0.5 L/min/(1 CFH) controlled |
Response time: | 95% in 30 sec @ 0.5 L/min/(1 CFH) |
Factory Calibration
H2Smart™ comes factory calibrated and is ready to use out of the box. To prolong its performance and ensure continued measurement accuracy, we recommend an annual factory calibration complete with certificate.
