變送器 的詳細介紹

Inputs LCA15變送器通用型稱重變送器多種輸出模塊（電壓/電流/數字）可供選擇輸入靈敏度范圍0.5-200mV 10V，160mA激勵，至多可驅動6只350歐姆傳感器 6線制連接用于遠距離補償全隔離4-20mA和0-10V輸出 2個固態繼電器設定點輸出 AC/DC供電可選數字顯示編程板透明ABS/鑄鋁外殼可選
The input is of the Load Cell/Strain Gauge type. With transducer excitation voltage of 9.6 volts @ 160mA to drive 6 x 350R bridges
Compensation by ± sense wires for cable and safety barrier losses down to 3V excitation
Load cell sensitivity is preset via DIL switches to 0.5, 0.8, 1.0 1.25, 1.5, 2.0, 2.5, 3.5, 5, 10, 20, 50, 100 or 200mV/V
Initial offset is no greater than ± 0.15mV (15uV/V) which is cancelled during auto calibration
Speed	is 10 readings per second with a digital filter to reduce speed
Accuracy	is 90 days ± 0.08% of reading, +/- 0.05% FSD being typical
Drift	is 0.002% per degree C @ 2.5mV/V typical
Resolution	15 bit/ 4.5 digits
Contact inputs	are available for auto tare, print and peak hold reset and are volt free
Analogue Outputs
Drive	4-20mA up to 1Kohm and 0-10 volts up to 2mA
Accuracy	4-20mA + 0.15% of range, typical. 0-10V ±2% before calibration
Resolution	as for display up to 13 bits/4.5 digits. Settling time 350mS to within 1% of step change
Isolation	±130V RMS or DC max to analogue input or any other port
Power Supplies
LS1	110V-120V AC or 220/230V AC 50-60Hz 10W
LS3	9-32V DC 10W isolated
Data Retention/Protection
Retention	10 years for set up values, minimum of 100,000 write cycles
Protection of data and function(s)	Watchdog timer giving repeat auto resets. Impending power detection and hold off. Keypad security and time out
