Cole-Parmer 80D-6 質量流量計

Cole-Parmer 80D-6 質量流量計

集成閥精確控制流量

使用三重校準的型號，多種氣體的應用

這些低成本的質量流量控制器使用熱氣體傳感技術,導致高度精確讀數和可重復性。校準的空氣，氦（He），氬（Ar）。有關更多信息，請致電我們的應用專家，

所有型號接受0到5伏直流電輸入信號的遠程閥控制。帶顯示屏的控制器還配備了一個電位器手動閥控制。顯示屏3 1/2-數字LCD和傾斜90°，便于觀看。前面板DIP開關讓你選擇一個工廠編程的氣體：空氣，氦氣或氬氣。

所有控制器都需要一個組合電源/輸入/輸出電纜。此電纜結合三種功能于一體：電源，附加0?5的直流電壓信號的輸入或輸出。使用遠程閥門控制的輸入信號，輸出信號用于數據采集或控制其它儀器。單獨訂購電源/輸入/輸出電纜。

防潮材料陽極化鋁，黃銅，316不銹鋼，氟橡膠?，和乙縮醛。每個控制器包含兩個縮醛壓縮接頭和一個24英寸長的網絡連接電線。最大壓降是15 psi的最大流量。壓差不應超過45磅。

精度：這些預校準的流量計，入口壓力在5 40磅，當操作氣體溫度介于64和77華氏度（18至25°C），而維持既定的±1.5％滿量程精度和線性度。超出5至40磅，加滿量程的±0.02％/ PSI;超出64至77°F（18至25°C），加±0.15％/°C滿刻度。

Integrated valve allows precise flow control

Use the triple-calibrated models for multiple gas applications

These low-cost mass controllers use a thermal gas flow sensing technique that results in highly accurate readings and repeatability. Model is calibrated for air, helium (He), and argon (Ar). Call our Application Specialists for more information. 

All models accept a 0 to 5 VDC input signal for remote valve control. Controllers with display also feature a potentiometer for manual valve control. Display is a 3 1/2-digit LCD and tilts up to 90° for easy viewing. Front panel dip switch lets you select one of the factory programmed gases: air, helium or argon. 

All controllers require a combined power supply/input/output cable. This cable combines three functions into one unit: power source, plus input or output of 0 to 5 VDC signals. Use the input signal for remote valve control; use the output signal for datalogging or controlling other instruments. Order the power supply/input/output cable separately.

Wetted materials are anodized aluminum, 316 stainless steel, brass, Viton?, and acetal. Each controller includes two acetal compression fittings and a 24" long cable with hub connector. Maximum pressure drop across the unit is 15 psi at maximum flow. Differential pressure should not exceed 45 psi. 

Accuracy: These precalibrated flowmeters operate at inlet pressures between 5 and 40 psi and at gas temperatures between 64 and 77°F (18 to 25°C) while maintaining the stated ±1.5% full scale accuracy and linearity. When operating beyond 5 to 40 psi, add ±0.02%/psi full scale; if operating beyond 64 to 77°F (18 to 25°C), add ±0.15%/°C full scale.
