Accurately measuring the masses of galaxy clusters is critical to the precise constraint of cosmological parameters from cluster surveys. The Sunyaev-Zel'dovich effect (SZE) is expected to be an excellent proxy for total cluster mass as it is relatively insensitive to the complicated physical processes internal to the cluster. The SZE also provides a unique opportunity for cluster surveys as the signal does not suffer from cosmological dimming. I present SZE observations taken with the 150 GHz APEX-SZ imaging camera; a 280 element transition edge sensor bolometer array mounted on the APEX telescope in northern Chile. Over the course of six observing campaigns we have acquired 575 hours of integration time on 36 targeted clusters. This sample contains both merging and relaxed clusters, and spans a wide range of redshifts and X-ray temperatures. I will present scaling relations relating the integrated SZE flux and X-ray temperature and (Y-TX) and compare them with predictions from numerical simulations.
