Введение продукции

This field calibrator combines a precision low-pressure reference, a fine-adjust pneumatic source and electrical measurement in one rugged handheld package. Technicians can apply controlled positive or negative differential pressure to room transmitters, switches and gauges while comparing the device output with the reference value. Step, hold and zero functions streamline multipoint verification.

Основные характеристики

Integrated hand pump generates controlled low positive or negative pressure.

Fine-adjust valve enables stable approach to each calibration point.

Dual pressure ports connect high and low sides of differential devices.

Simultaneous pressure and mA display supports transmitter verification.

Zero, hold and step functions simplify repeatable multipoint work.

Rugged field enclosure protects the reference sensor and controls.

Обеспокоенность клиентов продуктами

Cleanroom pressure instruments operate at small setpoints, so calibration equipment must generate pressure smoothly and compare pneumatic input with electrical output in a controlled sequence.

Low-pressure setpoints are difficult to reach without overshoot.A coarse hand pump and fine-adjust control allow gradual, stable approach to each point.

Separate reference, pump and loop meter create a complex field setup.One enclosure combines pressure generation, reference indication and electrical measurement.

Incorrect high/low connections reverse transmitter response.Color-coded dual ports make pressure polarity clear before the test begins.

Manual multipoint sequences can be inconsistent between technicians.Step, hold and zero functions standardize the applied-point workflow.
