LVDT/RVDT transmitter for industrial applications
Designed to deliver high-performance over a temperature range from -25 to +85°C, Measurement Specialties has developed a compact OEM signal conditioning transmitter. The LiM-420 operates on an 18-30V DC unipolar supply voltage and delivers a low noise 4-20mA current output signal.
The transmitter is compatible with many LVDT or RVDT transducers with five and six electrical connections and even with low input impedance. This makes the LiM-420 suitable for many general industrial applications such as valve position feedback, roller gap sensing, material testing machines and many others.
An easily-accessed DIP switch enables six selectable gain ranges while two 20-turn potentiometers allow for fine zero and gain adjustments for exact calibration. .
The generous excitation drive current of 20mA enables the board to operate with transducer impedances as low as 175Ω. Non-linearity is ±0.05% of Full Scale Output and stability is also ±0.05% of FSO after a 30 minute warm up. The board features a maximum supply current of 50mA and a maximum loop resistance of 500Ω (with a 24V DC supply). The maximum output noise and ripple is only 25µA RMS.
The LiM-420 can be either plugged directly into a backplane-style connector using the built-in card-edge guides or wired to the screw terminal barrier strip. The board can be mounted or stacked using the permanently-attached threaded standoffs or the card-edge guides.
