A pressure overload protector for a sensor includes a pressure-filled channel system fillable with fluid or gas, a first overload stop seated in an open position, a first diaphragm at the unseated end of the first overload stop, a second overload stop seated in an open position, a second diaphragm at the unseated end of the second overload stop, a sensor connected to a fluid channel, and a third and fourth overload stop connected by channels to the fluid channel of the sensor and terminating at a fluid exit. The overload protector provides bidirectional over and under pressure protection to the sensor.
