The 623H13TDE forms part of the MKS Instruments 623H series within the 600 Series Baratron capacitance manometer family. This model measures absolute pressure with high precision across a 1000 Torr full scale range. Its unheated ambient sensor design simplifies installation in vacuum systems. The NW16 ISO-KF fitting allows quick connection to standard vacuum hardware.
This manometer delivers 0.25% 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 easily with controllers and data acquisition systems. Two independent SPDT trip point relays let users configure process alarms or interlocks from 0.1% to 100% of full scale.
The 623H13TDE provides absolute pressure measurement across a 1000 Torr span. Accuracy stays within 0.25% of Reading under specified conditions. Resolution is 0.001% of Full Scale, supporting fine pressure monitoring in coarse vacuum ranges. A warm-up time of 30 minutes ensures stable operation after power-on.
Power requirements are +/-15 VDC (+/-5%) at 75 mA. The analog output delivers 0 to +10 VDC into loads above 10 kOhm. A terminal block connector with 5-post and 8-post strips handles all wiring. The two trip point relays are SPDT, rated 1 A at 30 VDC or 0.5 A at 30 VAC resistive. Trip relay source impedance is 12.5 kOhm maximum.
The overpressure limit is 45 psia (310 kPa). Internal volume is a compact 6.3 cc. The fitting is an NW16 ISO-KF type. Wetted materials include Incoloy and Inconel for corrosion resistance and vacuum compatibility.
The unit measures 3.00 inches (76.2 mm) in diameter with a body height of 3.75 inches (95.3 mm). The fitting stem extends 2.44 inches (61.9 mm). Operating temperature ranges from 0 to 50 degC. Zero temperature coefficient is 0.005% FS/degC, while span temperature coefficient is 0.04% of Reading/degC. The device carries CE compliance.
First, mount the 623H13TDE using the NW16 ISO-KF fitting on a compatible vacuum port. Ensure the O-ring and centering ring are clean before assembly. Next, connect the terminal block wiring according to the pinout diagram. Power the unit with +/-15 VDC and allow 30 minutes warm-up. Besides, verify the analog output with a calibrated voltmeter. Finally, adjust the two trip point relays using the potentiometers to the desired threshold between 0.1% and 100% FS.
Additionally, keep the sensor at ambient temperature and avoid direct heat sources. The unheated design means no thermal isolation is required. However, protect the unit from overpressure beyond 45 psia to prevent sensor damage. For process integration, route the relay outputs to your alarm panel or PLC input module.
