Product overview:

   apsl503 series automatic standard pressure generator is composed of the pressure controller host and the installation seat of the tested meter. It can be connected with three meters, the middle one can only be connected with a clean meter without liquid, the left and right two can be connected with meters with liquid, and a patented gas-liquid separator is set.

   apsl 503 series automatic standard pressure generator has a built-in pressure module, which can have a built-in Hart function to replace the Hart manual operator, set or calibrate the Hart transmitter range, force the Hart transmitter output current to a fixed value (such as 20mA, 12mA, 4mA), set the linear or square function, and can Hart reset the transmitter pressure sensor, which is more convenient to use than the Hart manual operator.

Performance index:

Working medium: air.

External air source: positive pressure: 1000kPa, negative pressure: -100kpa

Pressure module range: (-100 ~ 2500) kPa.

The vacuum can reach below -100kpa, and the micro pressure can be verified with a transmitter of ± 500pa

The diameter of the internal pipe is relatively large, and a gas-liquid separator is set, so it is not afraid of being carried with water or oil by the calibration meter

Measurement unit: kPa.

Pressure display resolution: 5 bits.

Pressure accuracy: level 0.02 or 0.05.

Current accuracy: 0.02 or 0.05.

Control stability: level 0.02: 3 words, level 0.05: 3 words

Target pressure stabilization duration > 2min。

Control response time < 30 seconds.

Control overshoot < 1% of the absolute value of the target pressure.

Standard verification point: the pressure transmitter is 0%, 25%, 50%, 75% and 100% of the measuring range, with automatic return. The connection computer can be set optionally. The pressure gauge is automatically divided according to the range and regulations.

Custom calibration range: (-100 ~ 2500) kPa.

Automatic voltage stabilization time: 15 seconds, adjustable between (10 ~ 240) seconds. The whole process time of transmitter automatic verification (voltage stabilization at 9:00): about minutes.

With HART manual operator function

Safety protection: overvoltage, overcurrent, sensor failure and other protection.

Current input: (1 ~ 2) circuits, (0 ~ 22) MA.

Loop power supply: dc24v/30ma. If it is connected to the standard meter by mistake, it will not damage the standard meter.

Pressure interface: m20*1.5 internal thread quick connector.

Current / voltage interface: Φ 4 standard banana plug.

Drain outlet: inner diameter: Φ 6mm。

Operating environment: -5 ℃ ~ 50 ℃.

Weight: 19kg.

Overall dimension: 200 (height) *400 (depth) *500 (width) mm.

Automatic verification software: optional.

External standard table: optional.

Automatic verification software: optional. It can be connected with tmms-2000 to automatically record the verification results and print the verification report.
