哥伦比亚模式的SA – 120RHT和SA – 125RHT力平加度成测测用于井下使用传感器以及服务应用。 模型的SA – 120RHT工作于± 15伏电源在温度可摄氏200度的力。 模型的SA – 125RHT± 5Vdc和工作于190摄氏度。 两种传感器是完全独立的并提供一个层次低抗出省去了温信号理的。
SA-125RHT
Columbia Models SA-120RHT and SA-125RHT Force Balance Accelerometers have been designed as Measurement While Drilling (MWD) sensors for use in downhole well service applications. The Model SA-120RHT operates from ±15 volts supply and is capable of operating at temperatures of up to 200 degrees Celsius. Model SA-125RHT requires ±5VDC and operates to 190 degrees Celsius. Both sensors are completely self-contained and provide a high level, low impedance output eliminating the need for high temperature signal conditioning.
