Depth of well is a set of two rotational sensors mounted on crown block. .The quadrature signal is applied to the input of electronic counter calibrated in meters.
The equipment consists of:
· Rotation sensors (2 pcs.)
· Reading disc (its function can be substituted by crown blocks rolls with 8 holes relief)
· Electronic indicator
· Mode optical and acoustic signaling
· Exi barrier
· Housing Exd
· Magnetic system to reset the counter and the two-stage activation prescribing
· Interconnection cables (Exi and Exd)
Depending on the desired resolution is selected number of blades read the disc (or the number of holes from crown block rollers).
