Danntech's new competitively priced loadcell transmitters provide 24-bit accuracy. These compact transmitters are configured to suit application requirements via a PC and configuration program.
Loadcell excitation is 2,5 or 5 volts with useable bridge resistances from 200 Ω upwards. Selectable input measurement ranges are ±20 mV, ±40 mV, ±80 mV, ±160 mV, ±320 mV, ±640 mV, ±1.280 V and ±2.560 V. Various output types can be chosen from 4 to 20 mA, 0 to 20 mA, 0 to 5 V, 0 to 10 V, ±5 V and ±10 V.
Using the powerful configuration software, the transmitter can have any part of any of the input ranges mapped to any output range. For example if 0 to 100 kg produces a millivolt input range of +5 to 47 mV then this can be set up to produce an output of 12 to 20 mA if required.
The two relay outputs can be configured as alarms with selectable operating sense and hysteresis. A simple ASCII protocol is used on RS485 to connect multiple units a control module or a control system.
The transmitter can be used in a passive mode, where it operates like a remote terminal unit (RTU) with a 24-bit loadcell input, a 12-bit analog output, two relay outputs and two LED outputs each individually controllable.
The unit is 24 V d.c. powered and three way isolation up to 1000 V a.c. ensures trouble-free operation in process control environments where ground loops and noise may be prevalent.
The four input version is available with five isolated 4-20 mA outputs, one for each loadcell input and one for the summation of all the inputs. In addition to this, a summed and simulated loadcell output is available so that this transmitter can appear to an existing loadcell system, as if it was simply four loadcells hardwired in parallel.
