APSL801 Pneumatic Fully Automatic Piston Pressure Gauge
Overview
The APSL801 Pneumatic Fully Automatic Piston Pressure Gauge is developed from the invention patents "A Wear-Resistant Fully Automatic Piston Pressure Gauge" (ZL201910276297.7), "A Wear-Resistant Absolute-Pressure Fully Automatic Piston Pressure Gauge" (ZL202122144084.4) and "A Positive-Negative Pressure Fully Automatic Piston Pressure Gauge and Method of Use" (202210010954.5). It consists of a fully automatic piston pressure gauge host and a pressure controller, achieving fully automatic weight loading and simultaneous fully automatic pressurization. Wear resistance is maintained at all times so the piston system's maximum error stays within tolerance throughout a verification cycle. Incorporating the functions of a fully automatic pressure calibration platform, it supplies 24 V power and measures real-time pressure, input current, input voltage, piston position, weight rotation speed, piston-head temperature and humidity, verifying pressure transmitters, digital pressure gauges and precision pressure gauges fully automatically with user-set verification points—two transmitters take only about 8 minutes. Setpoints can be stepped via the "setpoint increase/decrease" keys by a freely adjustable control step or entered on the touchscreen; the descent rate is calculated automatically once the piston floats, weights rotate automatically during control and stop when control stops, and 2–4 current channels are measured to verify 2–4 transmitters at once. The pneumatic family includes positive-pressure, positive-negative-pressure, absolute-pressure and zero-start micro-pressure versions. Accuracy: pressure Class 0.005/0.01/0.02/0.05; current (0–22) mA Class 0.02; voltage (0–5.5) V Class 0.02. Positive-pressure ranges (2–160) kPa to (200–10000) kPa. Weights use non-magnetic stainless steel, piston rod/cylinder use tungsten carbide, working medium is nitrogen, and it connects to TMMS-2000 software for automatic report printing. Standard gas-liquid separator; remote control via serial port or WiFi; video-playback function. Complies with JJG1086-2013 and JJG99-2006.
