Temperature Gauge reading low

My 87 Lebaron GTS temperature gauge seems to read low. I have the digital cluster, it shows only 3 bars on the gauge, which is outside what is usually the normal operating range. The engine seems to get to normal temp and doesn't overheat and hot air comes out of the vents. I have replaced the thermostat and the sending unit. With the new sending unit the gauge still reads the same. Could it be the gauge itself, a wiring issue or something completely else.
