Internal or External pressure Transducer
0-20bar / 0-200 metres head / 0-300 psig standard (other ranges available)
Please note that the logger is calibrated to 10 bar as standard. 20 bar calibration must
be specified at time of order if required. <0.2% FSD accuracy supplied as standard.
<0.1% FSD accuracy available as optional enhancement if required. Please specify at
order.
4-20mA from isolated sensor
Please note only one analogue channel can be 4-20mA
Capacity
Memory
Recording 16,000 readings in continuous (cyclic) operation. Unit can be purchased with
optional extended memory to 32,000 readings. An optional compressed firmware
version can enable storage of up to 1,000,000 data values depending on variability of
data. Please note that the correct configuration must be ordered at the time of
purchase as changes cannot be made after manufacture.
