APSL503Hydraulic Intelligent Pressure Controller

1. Product Overview:

The APSL Type 503 Series Hydraulic Intelligent Pressure Controller (Automatic Standard Pressure Generator) consists of the pressure controller main unit and a mounting seat for the gauge under test, and can connect two gauges.

APSL type 503 seriesSmart pressure controller(Automatic standard pressure generator) Built-in pressure module, can have built-in HART function, replacing HART hand-held terminal, setting or calibrating HART transmitter range, forcing HART transmitter output current to a fixed value (such as20mA、12mA、4mA), setting linear or square root function, can perform HART zeroing on transmitter pressure sensor, more convenient to use than HART hand-held terminal.

2. Performance Features:

• Built-in pressure module, external pressure modules can be expanded;

• Built-in pressure source, fully automatic output of set pressure;

• Uses piston cylinder for rapid pressurization and stabilization, fast pressurization and stabilization speed;

• Can verify and calibrate Hart pressure instruments;

• Built-in voltage, current measurement andDC24V power supply;

• Touch color screen + function keys, supports WiFi and other communication methods;

• Has anti-clogging sewage discharge function.

3. Performance indicators:

4. Fully automatic verification:

• Can verify two pressure transmitters, automatically record and print verification records;

• Can verify digital pressure gauges, optional automatic identification device;

• Can verify precision pressure gauges, automatically calculate errors, and automatically print verification reports;

• Verify ordinary pressure gauges, with 1/5 estimation reading for pressure gauges, quick input of light tap variation and indication value, and automatically print verification records and reports.

• 

Verify electric contact pressure, can automatically test the upper and lower switching values of the double needle, and automatically calculate the error and switching difference. When verifying the indication value, complete a set of upper and lower switching values of the double needle synchronously.
