Columbia Models SA-220RHT and SA-225RHT Force Balance Accelerometers have been designed as Measurement While Drilling (MWD) sensors for use In down hole well service applications.The Model SA-220RHT operates from Â±15VDC and is capable of operating at temperatures of up to 200°C. Model SA-225RHT requires ±5VDC and operates to 190°C. Both sensors are completely self-contained and provide a high level, low Impedance output eliminating the need for high temperature signal conditioning.
In addition to exceptional high temperature performance, rugged construction and lOW° power consumption have made the SA-220RHT and SA-225RHT sensors the accepted standard for use in down hole high temperature mapping.
