The 624H12TCECU belongs to the MKS Instruments 624H series within the 600 Series Baratron family. This heated model controls its sensor temperature to 45 degC, which prevents process byproduct condensation on the diaphragm. Such thermal stability proves essential in semiconductor etch and deposition processes. The 100 Torr full scale range suits medium vacuum applications that demand tight pressure control.
This manometer achieves 0.12% of reading accuracy, covering non-linearity, hysteresis, and non-repeatability. Resolution reaches 0.001% of full scale. Moreover, the 0 to +10 VDC analog output integrates cleanly with system controllers. Two SPDT trip point relays each accept a 0.01 to 10 VDC level signal, enabling flexible process interlock configuration.
The 624H12TCECU provides absolute pressure measurement across a 100 Torr span. Accuracy stays within 0.12% of Reading, the tightest tolerance in this series. Resolution is 0.001% of Full Scale. A warm-up time of 2 hours allows the heated sensor to reach thermal equilibrium before critical measurements.
Power requirements are +/-15 VDC (+/-5%) at 0.40 A maximum. The analog output delivers 0 to +10 VDC into loads above 10 kOhm. A terminal block adaptor handles all wiring connections. Each trip point accepts a 0.01 to 10 VDC level signal. The two relays are SPDT, rated 1 A at 30 VDC or 0.5 A at 30 VAC resistive, with source impedance at 12.5 kOhm maximum.
The overpressure limit is 45 psia (310 kPa). Internal volume is a compact 6.3 cc. The fitting is an 8 VCR female type. Wetted materials consist of Inconel, which offers excellent corrosion resistance at elevated sensor temperatures.
The unit measures 3.15 inches (80.0 mm) in diameter with a body height of 3.87 inches (98.3 mm). The stem extends 1.38 inches (35.1 mm). Operating temperature ranges from 15 to 40 degC. Zero temperature coefficient is 0.002% FS/degC, while span temperature coefficient is 0.02% of Reading/degC. The device carries CE compliance.
First, mount the 624H12TCECU using the 8 VCR female fitting on a compatible vacuum line. Ensure mating surfaces are clean and undamaged. Next, connect the terminal block adaptor wiring per the pinout diagram. Power the unit with +/-15 VDC and allow 2 hours warm-up so the 45 degC sensor stabilizes. Besides, verify the analog output with a calibrated voltmeter. Finally, configure each trip point by applying the desired 0.01 to 10 VDC level signal.
Additionally, maintain ambient temperature between 15 and 40 degC for rated accuracy. The heated sensor needs no external thermal jacket, yet keep it away from strong drafts. However, never exceed 45 psia overpressure to protect the diaphragm. For process integration, route relay outputs to your alarm panel or PLC input module.
