PFEA111-65/3BSE050090R65工业自动化卡件
我们制造和销售的仪器（AA375R、AA475R、AA575R、BC350R、BC450R、BC550R、GT300R、GT400R和GT500R）在正常使用和服务条件下无材料和工艺缺陷。如果温度计暴露于以下环境或通过制造过程受到以下腐蚀性化学品的影响，则本保修无效：（1）腐蚀性化学品；（2） 超过额定超温限值的温度；或（3）使温度计过度振动或导致阀杆或外壳损坏的任何应用。我方在本保证项下的义务仅限于维修或更换任何温度计，该温度计应在购买之日起八（8）年内返还我方工厂，预付运输费，并且我方检查应发现该温度计因工艺或材料而存在缺陷。本保证明确代替所有其他明示或暗示的保证（包括适销性和特定用途适用性的保证），以及我方对因使用或误用本温度计而造成的损害（包括但不限于间接损害）的所有其他义务或责任，我方不承担任何责任，或授权任何其他人承担与销售本温度计或其任何部分相关的任何其他责任。在上述相同条件下，所有其他车型的保修期为一年。➤ 检查双金属温度计校准的建议：建议使用主温度计（至少与双金属温度计一样准确）进行比较。为了获得最佳结果，请使用经NIST直接认证的精密ASTM型玻璃水银温度计。双金属温度计杆浸入介质中的深度必须至少达到杆上的凹槽，以确保整个双金属线圈浸入。在一些短杆Tel-Tru工业温度计中，凹槽可能被螺纹连接隐藏；在这种情况下，整个阀杆和螺纹都应该浸入其中。校准测试设备注意事项：检查该仪器的稳定性和精度规范，并用NIST可追踪的玻璃水银温度计交叉检查读数。确保测试仪器在读数点稳定，因为最初将温度计杆插入浴槽/干燥块有时会对测试装置的稳定性产生短期影响。当指针稳定并停止移动时，读取双金属温度计的读数。典型的浸没时间可能从大约1到3分钟不等，具体取决于所用的温度计类型、温度点和校准测试设备。建议使用实验室级恒温槽，并进行搅拌，以提供均匀的温度。控制装置和读数（如果提供）应进行适当校准，且至少与所测试的双金属温度计一样准确
instruments (AA375R, AA475R, AA575R, BC350R, BC450R, BC550R, GT300R, GT400R, and GT500R) manufactured and sold by us to be free from defects in material and workmanship under normal use and service. This warranty shall be null and void if the thermometer is exposed or subjected to: (1) corrosive chemicals, either environmentally or through manufacturing processes; (2) temperatures in excess of the rated over-temperature limit; or (3) any application which subjects the thermometer to excessive vibration or causes violation of the stem or case enclosure. Our obligation under this warranty shall be limited to the repair or exchange of any thermometer which shall be returned to our factory, transportation charges prepaid, within eight (8) years of the date of purchase, and which our examination shall disclose to be defective due to workmanship or material. This warranty is expressly in lieu of all other warranties expressed or implied (including any warranty of merchantability and fitness for a particular purpose), and of all other obligations or liabilities on our part for damages, including but not limited to consequential damages, arising out of the use or misuse of this thermometer, and we neither assume, or authorize any other person to assume for use, any other liability in connection with the sale of this thermometer or any part thereof. Warranty on all other models is one year under the same conditions as noted above. ➤ RECOMMENDATIONS FOR CHECKING THE CALIBRATION OF BIMETAL THERMOMETERS: Use of a MASTER THERMOMETER, at least as accurate as a bimetal thermometer, is recommended for making comparisons. For best results, use a precision ASTM type mercury-in-glass thermometer certified directly traceable to NIST. Immersion of the bimetal thermometer stem into the medium must be at least up to the groove on the stem to assure that the entire bimetal coil is immersed. In some short stem Tel-Tru industrial thermometers the groove may be hidden by the threaded connection; the entire stem and thread should be immersed in this case. CALIBRATION TEST EQUIPMENT CONSIDERATIONS: Check the stability and accuracy specifications of this instrumentation, and cross-check the read-outs with NIST traceable mercury in glass thermometers. Make certain the test instrument is stabilized at the reading point as initial insertion of thermometer stem into bath/dry block can sometimes have a short-term affect on test device stability. Take reading of Bimetal Thermometer when the pointer has stabilized and stopped moving. Typical immersion time may vary from approximately 1 to 3 minutes depending on type of thermometer, temperature point and calibration test equipment used. Use of a laboratory grade CONSTANT TEMPERATURE BATH, with agitation to provide uniform temperature throughout, is recommended. Controls and read-out (if provided) should be properly calibrated and at least as accurate as the bimetal thermometer being tested
