Druck DPI 615LP 20INH2O 便携式压力校验仪

Druck DPI 615LP 20INH2O 便携式压力校验仪

用来校准压力变送器从真空到300 psi

低压型号量程的±0.05％精度和范围±1" H2O to 60"H20

高压模精度±0.025％满量程

选择低高压记录和非记录校准器

高压力校准器内置泵易于压力产生，音量调节器净压控制。低压校准器内置双活塞音量调节器course压力/净压设置。压力释放阀去除截留的空气，而不需要断开被测设备。防护等级为NEMA 12（IP54）的坚固箱子，合成橡胶键盘是专为工业设计或现场使用。可测量25个不同的单位的压力，其中包括用户自定义刻度。双显示器显示电流，电压，温度，和最小/最大读数。任务菜单提供了选择压力变送器校准，压力开关测试，泄漏测试，循环测试，故障查找。为了帮助校准和测试，校准器提供10 VDC，24 VDC，和高达24 mA。

型号68974-12至-18和-48〜-58存储多达10,000个读数，通过RS-232端口可将数据发送到计算机上。 型号68974-40至-46和-60〜70功能双向PC通信传输程序和结果，以及误差分析，通过/失败状态。从PC上下载的程序会自动配置校准器预定义的校准和测试例程。可选的软件是必需的。单独订购。

低压设计上可现场校准非常低的压力传感器。低压差，即使连接在测试设备可感应显着压力。为了弥补这一点，提供一个“自动调零”设施，它使用一个内部的电磁阀，零点校正前均衡压力差。

Designed to calibrate pressure transmitters from vacuum to 300 psi

Low-pressure models have accuracy of ±0.05% of span and ranges of ±1" H2O to 60"H20

High-pressure models have accuracy of ±0.025% full-scale

Choose from documenting and non-documenting calibrators in low or high pressure ranges

High-pressure calibrators include built-in pump for ease of pressure generation, and the volume adjuster for fine pressure control. Low-pressure calibrator includes a built-in dual piston volume adjuster for course/fine pressure settings. The pressure relief valve removes trapped air without the need to disconnect the device under test.Rugged NEMA 12 (IP54) case with elastomer keypad is designed for industrial or field use. Measure pressure in 25 different units including a user-definable scale. Dual display indicates current, voltage, temperature, and minimum/maximum readings. The TASK menu provides options for pressure transmitter calibration, pressure switch testing, leak testing, loop testing, and fault finding. To aid calibration and testing, calibrators supply 10 VDC, 24 VDC, and up to 24 mA.Models 68974-12 to -18 and -48 to -58 store up to 10,000 readings and send the data to a computer via a RS-232 port. Models 68974-40 to -46 and -60 to 70 feature two-way PC communication for transferring procedures and results, as well as error analysis with pass/fail status. Procedures downloaded from a PC automatically configure the calibrators to pre-defined calibration and test routines. Optional software is required. Order seperately below.

The Low-Pressure units are designed on-site calibrateion of very low pressure sensors. At low differential pressures, even connecting the device under test can induce significant pressure. To compensate for this, an “auto zero” facility is provided which uses an internal solenoid valve to equalize the differential pressure prior to zero correction.
