GY-GSG Polish Rod Diagram Indicator tests the variation of the load according to the alternation of the diameter of the polish rod of the pumping unit. It tests displacement through acceleration integration to measure parameters, such as the indicator diagram (dynagraph card) of the pumping unit.

Parameters:

• Working temperature range :  -40℃～+65℃
• Load difference measurement range:  0～240 KN
• Load difference measurement error :  5%/1KN
• Displacement measurement range :  0～15m
• Displacement measurement error/1cm:  5%/1cm
• Wireless communication distance:  ≥30m（open area）
• Continuous working time :  ≥16 hours
• Usable range: Stroke ＞ twice/Min
• Usable polish rod 12.8mm～39mm
