FTC300
FTC300
- Measurement Range: Capable of measuring a wide range of gas mixtures including H2, He, CO2, CH4 in N2 or Ar, and N2 in Ar.
- Sensitivity: High sensitivity with a range of 0-0.5 Vol.% H2 in N2 and low noise levels below 10ppm H2 in N2.
- Calibration: Offers classic 2-point calibration or simple one-gas calibration with customizable linearization up to sixth order polynomial.
- Output: Isolated 4-20mA output, expandable with a free set of start and end within a 100 Vol.% range.
- Response Time: Fast response with a T90-time of less than 1 second depending on flow rate.
- Construction: Pressure proof up to 20bar and vacuum leak-tight stainless steel gas duct.
- Communication: RS 232 access to all values and parameters, with digital output resolution of 1ppm over the whole 100Vol.% range.
- Multi Gas Mode: Allows sequential indication of up to 15 binary mixtures.
- Cross Sensitivity Compensation: Achieved through external signal input and internal calculation.
- PC-based Service Program: Simplifies settings, linearization, and calibration.
- Robust Design: Small and robust transmitter housed in aluminum for field use, with protection class IP65.
- Dimensions: 145mm x 80mm x 85mm; weight up to 1800g.
- Power Supply: 24V DC (18V to 36V), 700mA.
- Ambient Temperature Range: -5°C to 50°C, with other ranges available on request.
- Linearity: Less than 1% of range.
- Flow Rate: Recommended 60l/h - 80l/h, with a range of 40l/h to 150l/h.
- Noise and Drift: Noise less than 1% of the smallest range, drift at zero point less than 2% of the smallest range per week.
- Pressure: Maximum gas pressure of 2MPa (20bar).
