Cavity modes can serve as detector of quantum simulators. Here we examine how a cavity's correlator changes when coupled to one of two quantum simulators: a qubit and the transverse field Ising model using a diagrammatic technique. Using this approach, we determine whether reliable detection of the simulator's many-body correlator can be achieved. We also calculate the backaction of the detector on the quantum simulators. In the case of the qubit, this allows us to obtain a simple expression for the cavity correlator without the need for the rotating wave approximation.
