SWAIN METER電流表Auto MER介紹
Swain Auto MER直流電流鉗表是一種用于腐蝕檢測的測試儀表，具有自動量程和自動歸零功能。 MER? 代表減少磁誤差。
Pelican外殼設計防水，并使用防塵、軍用風格、Cannon 連接器。數(shù)據記錄輸出插孔是所有 Auto MER和MER儀表的標準項目。
特征：
可選配外部電源。
測量范圍是自動選擇的——通常是 2、20或200 A，在輸入電流變化的幾秒鐘內。零位也是自動和精確設置的。
Auto MER型直流電流鉗通常更準確。它們的構造可顯著減少由于傳輸線管道中的剩磁或車輛中的磁鐵引起的零偏移誤差。與可比較的標準 Swain Meters 相比，優(yōu)點是二或三比一。
測量電流的極性（流向）顯示在LCD儀表和輸出端子上。
Auto MER完全便攜，可使用50小時。顯示電池和“低電量”圖標。
在“自動”中，量程選擇、調零和電池關閉都是自動的。
在“手動”中，選擇范圍并手動設置歸零。電池電量保持開啟。
外接電池是可選的。
分辨率：0-2Amp范圍為1mA，0-20Amp范圍為20mA，0-200Amp范圍為100mA分辨率。
內徑為 24" 至 60" 的夾具具有 10 mA 的分辨率。
精度為 ±1% 讀數(shù)，±3位，由于磁性造成的±零偏移。LCD儀表有3 ?位數(shù)字和 ?”高數(shù)字。
在任何范圍內，記錄儀的輸出在滿量程輸入時為±2 V。超量程可用。交流輸入電流在10 A rms – 60 Hz輸入時被拒絕變化小于5 mA。
The Swain Auto MER DC Current Clamp Meter is a test meter for corrosion detection that features auto ranging and auto zeroing. MER stands for Magnetic Error Reduction.
Pelican brand case design is water resistant and uses dust proof, military style, Cannon Connectors. Data logging output jacks are a standard item on all Auto MER and MER Meters.
Features:
Optional external power source available.
Measurement range is selected automatically — typically 2, 20, or 200 A., within seconds of a change of input current. Zero is also automatically and precisely set.
Auto MER model DC Amp Current Clips are generally more accurate. They are constructed to substantially reduce zero offset error due to residual magnetism in transmission line pipe, or magnets in vehicles. The benefit is usually two or three to one over comparable standard Swain Meters.
Polarity (direction of flow) of measured current is shown both on the LCD meter and also at the output terminals.
Auto MER is fully portable, with 50 hr. battery and “Low Batt” icon.
In “Auto”, Range selection, Zero adjustment, and also battery OFF are automatic.
In “Manual”, Range is selected and Zero is set by hand. Battery power stays on.
External Battery is optional.
Resolution: 0-2Amp range is 1mA, Zero to 20Amp range is 20mA, Zero to 200Amp range is 100mA MAX resolution.
Clamps with 24″ to 60″ inside diameter have 10 mA max. resolution.
Accuracy is ±1% reading, ±3 digits, ± zero offset due to magnetism. The LCD meter has 3? digits with ?” high numerals.
Output for a recorder is ±2 V at full scale input on any range. Overrange is available. AC input current is rejected to less than 5 mA change with 10 A rms – 60 Hz input.
SWAIN METER傳感器MER2介紹
MER2 DC Amp Clips和Clamps是“Swain 傳感器”，可在正常操作期間精確檢測磁化導體上流動的直流電流的大小和方向，而不會中斷電路。用于地面和海底陰極保護的 Swain 便攜式直流夾的直徑為2英寸到10英寸。Swain夾具是兩件式傳感器，直徑從6英寸到60英寸不等�？筛鶕笾圃旄蟮膴A具。夾具以4件部分制造，尺寸大于60英寸。
MER2型（雙倍磁誤差減少）直流電流鉗通常更準確地用于使用非接觸式傳感器測量直流電。它們的構造是為了減少由于鋼管、鋼筋附近或汽車和卡車電池附近常見的不均勻磁場引起的誤差。零偏移誤差通常小于可比標準Swain Meters的四分之一。
典型精度為± 1% 讀數(shù)、± 3 位、± He。用戶友好的3 1/2 位LCD儀表，極性和1/2"高數(shù)字。（他是傳感器對地球磁場的零偏移靈敏度。除非鋼靠近并扭曲它，否則地球磁場是均勻的。附近有強磁鐵也可能導致零偏移。）
防止300 A過載
MER2 DC Amp Clips and Clamps are “Swain Sensors” which precisely detect the magnitude and direction of direct current flowing on magnetized conductors during normal operation without interrupting the circuit. Swain portable DC amp clips for cathodic protection above ground and sub sea are manufactured from 2″ to 10″ in diameter. Swain clamps are two piece sensors manufactured from 6″ to 60″ in diameter. Larger clamps may be built upon request.Clamps are manufactured in 4 piece sections for sizes greater than 60″.
MER2 (Magnetic Error Reduction doubled) type DC Amp Clips are generally more accurate for measuring direct current with a non-contact sensor. They are constructed to reduce errors due to non-uniform magnetic fields common on steel pipe, near rebar, or near the battery in cars and trucks. Zero offset error is generally less than one quarter that of comparable standard Swain Meters.
Typical accuracy is ± 1% reading, ± 3 digits, ± He. User friendly 31/2 digit LCD meter with polarity & 1/2″ high numerals.(He is zero offset sensitivity of the sensor to the earth’s magnetic field. The earth field is uniform unless steel is close and distorts it. A strong magnet nearby can also cause zero offset.)
Protected from 300 A overload.
