Our published instructions assume that users are reading these 2K ohm RTDs using DGSI readouts or the Campbell Scientific CR10X with AVW1 or AVW100 vibrating wire interface.
If you are using another device to read these sensors, obtain a reading in K ohms. Then apply either of the following polynomial coefficients to obtain degrees C:
Solution A: For a range of -10 to +30 C.
Ax2 + Bx + C, where x is the reading in K ohms, and:
A = -23.508334394
B = 227.625006633
C = -341.217356436
Solution B: For a range of -50 to 120 C.
Ax5 + Bx4 + Cx3 + Dx2 + Ex + F, where x is the reading in K ohms, and:
A = 0.95659
B = -12.65962
C = 70.30009
D = -216.32308
E = 483.85218
F = -472.87637
