Technical Report WRD92039 Viewed at 15:07:17 on 29/07/2010 Page 99 of 192. (i) water Level Transducers - accuracy (linearity) to within 0.1% of full scale - 4-20 rna output - temperature compensation - operating temperature range -10 - 60Ge - cable required to enable ease of handling and reasonably resistant to crushing, crimping, severence and chemical corrosion (some subjective assessment required) - cable capable of at least SOm unsupported downhole - adequate venting efficiency (if vented transducer) - waterproof vent seal of vented cable - durable and robust construction of transducer and she,ath should be of inert material (some subjective assessment required) - non-bouyant and adequately weighted to maintain straightness of assembly downhole - waterproof connection with logger - maximum outer diameter 40mm (ii) Barometric Transducers - accuracy (linearity) to within 0.1% of full scale - 4-20 ma output - ten~erature compensation - operating temperature range -10 - 600e - desirable 80 - 100% humidity resistant - transducer and sheath of inert construction - durable and robust construction (iii) Flow (piezometric) Transducer - accuracy (linearity) to VIi thin 0.1% of full scale - 4-20 rna output - temperature compensation - op~lrating temperature range -10 - 60Ge - desirable 80 - 100% humidity resistant - tnmsducer of inert construction - durable and robust construction - desirable lightweight and portable
