哥倫比亞模式的SA – 120RHT和SA – 125RHT力平加度成測測用于井下使用傳感器以及服務應用。 模型的SA – 120RHT工作于± 15伏電源在溫度可攝氏200度的力。 模型的SA – 125RHT± 5Vdc和工作于190攝氏度。 兩種傳感器是完全獨立的并提供一個層次低抗出省去了溫信號理的。
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.
