VX超聲波聲速儀 VX
VX美國(guó)DAKOTA超聲波聲速儀
DAKOTA公司VX是一種手持式超聲波聲速測(cè)定儀(球化率儀)。當(dāng)被測(cè)定的材料是鑄件、合金或者塑料時(shí),VX就會(huì)測(cè)出聲波穿過(guò)它們時(shí)的速度。因此,可得出所測(cè)材料內(nèi)部組織是否緊密無(wú)缺陷。 如可預(yù)先將球墨鑄鐵不同球化率百分比(通過(guò)金相法)試樣做出,分別測(cè)量其不同的聲速值,對(duì)鑄件進(jìn)行批量檢查。

顯示 4.5位液晶顯示屏; 顯示讀數(shù)高為0.5英寸; 背光可選開(kāi)/關(guān)/自動(dòng); 測(cè)量值以英寸/微秒或米/秒顯示; 條形圖指示讀數(shù)穩(wěn)定。 電源 2節(jié)1.5V堿性電池或1.2vAA鎳鎘電池。 堿電池可用200小時(shí)。鎳鎘電池可用130小時(shí)。當(dāng)電量低時(shí),顯示屏?xí)W爍;當(dāng)電池電量太低以致儀器不能可靠工作時(shí),儀器會(huì)自動(dòng)關(guān)閉。 物理參數(shù) 重量:300g(帶電池) 外形:63.5x114.3x31.5mm 外殼:擠壓鋁機(jī)殼,底蓋用鍍鎳鋁板加密封墊封裝。 鍵盤(pán) 6個(gè)反饋式按鍵; 有密封覆膜; 防水和耐油。 探頭 頻率范圍:1~10MHz 雙晶探頭 快鎖式LEMO接口,1.2米長(zhǎng)電纜(可提供用戶特需探頭) |
VX ultrasonic sound velocity meter VX
VX America DAKOTA ultrasonic velocimeter DAKOTA company VX is a portable ultrasonic tester(spheroidization rate meter). When the measured material is casting, alloy or plastic, VX will measure the speed ofsound through them. Therefore, can be drawn from the measured material internal organization is close without defects. Such as can advance into the nodular cast irondifferent nodularity percentage (by Jin Xiangfa) samples,we measured the different sound speed value, batchinspection of castings.
Measurement
Measuring range: 0.63 ~ 500mm (can choose imperial orMetric)
Resolution: 0.01mm
Speed range: 1250 ~ 10000m/s;
Single point measurements of 4 readings per second;
Scanning measurement per 16 readings;
The single point measurement model checking of known thickness or sound.
Display
4.5 liquid crystal display;
Display reading high is 0.5 inches;
Backlight optional on / off / auto;
Measured in inches / s or M / s display;
The bar graph indicates the stable reading.
Power Supply
2 1.5V alkaline battery or 1.2vAA nickel cadmium battery.
Alkali battery available for 200 hours. Nickel cadmiumbattery available 130 hours. When the power is low, the display flashes; when the battery power is too low so that the instrument can not work reliably, the instrument willautomatically shut down.
