Druck DPI 615LP 20INH2O 便攜式壓力校驗儀

Druck DPI 615LP 20INH2O 便攜式壓力校驗儀

用來校準壓力變送器從真空到300 psi

低壓型號量程的±0.05％精度和范圍±1" H2O to 60"H20

高壓模精度±0.025％滿量程

選擇低高壓記錄和非記錄校準器

高壓力校準器內(nèi)置泵易于壓力產(chǎn)生，音量調(diào)節(jié)器凈壓控制。低壓校準器內(nèi)置雙活塞音量調(diào)節(jié)器course壓力/凈壓設置。壓力釋放閥去除截留的空氣，而不需要斷開被測設備。防護等級為NEMA 12（IP54）的堅固箱子，合成橡膠鍵盤是專為工業(yè)設計或現(xiàn)場使用。可測量25個不同的單位的壓力，其中包括用戶自定義刻度。雙顯示器顯示電流，電壓，溫度，和最小/最大讀數(shù)。任務菜單提供了選擇壓力變送器校準，壓力開關測試，泄漏測試，循環(huán)測試，故障查找。為了幫助校準和測試，校準器提供10 VDC，24 VDC，和高達24 mA。

型號68974-12至-18和-48?-58存儲多達10,000個讀數(shù)，通過RS-232端口可將數(shù)據(jù)發(fā)送到計算機上。 型號68974-40至-46和-60?70功能雙向PC通信傳輸程序和結果，以及誤差分析，通過/失敗狀態(tài)。從PC上下載的程序會自動配置校準器預定義的校準和測試例程。可選的軟件是必需的。單獨訂購。

低壓設計上可現(xiàn)場校準非常低的壓力傳感器。低壓差，即使連接在測試設備可感應顯著壓力。為了彌補這一點，提供一個“自動調(diào)零”設施，它使用一個內(nèi)部的電磁閥，零點校正前均衡壓力差。

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.
