PID Analyzers - Model 204 -Thermal Conductivity Analyzer for Process and QC Monitoring
The Model 204 is a continuous TCD Analyzer designed for continuous or process control. It has optional 4-20 mA output, RS485, MODBUS, 2-3 programmable setpoints, larger pump, bypass flow & and a 19`` rack or industrial wall mount NEMA 4 enclosure. This 204 has a rugged TCD with a sealed reference cell, Operator`s Manual, configuration software and RS232 cable. The detector is the TCD.

- TCD: Our very stable TCD has a sealed reference to minimize maintenance.
- ADC: Our 16 bit ADC provides a resolution of 1 part in 64,000 and our signal algorithm minimizes noise by signal averaging in the msec range./td>
- Enclosures: 19`` rack mount or NEMA 4 wall mount.
- Programmable Voltage/current output: 0-1VDC/4-20 mA.
- Ease of calibration - SemiAutomatic or Remote Automatic: The two point calibration for the TCD uses a zero gas and a span gas. It is initiated by a push button switch. The time to calibrate is about 1 minute. The FID requires zero air and span gas for calibration. In the 204, the calibration valves are built into the Analyzer. The remote calibration can be activated by a PLC controlled contact closure.
- Digital outputs: RS485, MODBUS.
- Display: Our 2 line by 16 character display is backlit. The upper display provides the concentration and the bottom display provides the sensor, units, alarm and logging mode. For multisensor units, a 3 readout LED is used.
- Programmable setpoints: The 1-3 setpoints (depends on the options) can be programmed for PID control, above/below setpoints.
- Species measured: He, H2, Ne, CO2, binary gases with a difference in thermal conductivity is required
