Model 2120 Shaft Reaction Torque Sensor DESCRIPTION Model 2120 shaft reaction torque sensor is designed for instal- cial machined portion of the transducer to achieve a maximum lation between test pieces such as motors, switches, axles, or non-linearity of 0.1% over a wide dynamic range. Typical ap- shafts and their mounting plate. These models operate and are plications include tire braking, motor dynamometers, friction-skid calibrated in both directions. Nickel-plated alloy steel enhances testing, and twist measurement. 50 in-oz to 1000 in-oz capaci- durability in harsh, industrial environments. These models have ties. no moving parts and utilize four bonded strain gages on a spe- FEATURES • 50 in-oz to 1000 in-oz capacities • 0.1 % non-linearity and hysteresis • No maintenance of slip rings, bearings, or brushes • Low-end sensitivity • Reaction measurement designed to eliminate speed limitations Model 2120 PERFORMANCE SPECIFICATIONS Characteristic Measure Torque range 50, 100, 200, 500, 1000 oz-in Non-linearity ±0.1 % of rated output Hysteresis ±0.1 % of rated output Repeatability ±0.05 % of rated output Output @ rated capacity 2 mV/V (nominal) TYPICAL SYSTEM DIAGRAM Customer Supplied Chart Recorder Alarm Panel Data Acquisition Computer PLC In-Line Amplifiers (Used with unamplified units only) Output Amplifier Universal In-Line Amplifiers +/-5 VDC UV +/-10 VDC UV-10 0 +/-5 VDC UBP 4-20mA (3 wire) U3W 4-20mA (2 wire) U2W DIN rail Mount In-Line Amplifiers 0 +/- 5 VDC (3 wire) DV-05 4-20mA (3 wire) DA-05 0 +/- 10 VDC (3 wire) DV10 Power Supply Honeywell In-Line Amplifier Output Input Serial Number ENVIRONMENTAL SPECIFICATIONS Characteristic Measure Temperature, operating -54 °C to 93 °C [-65 °F to 200 °F] Temperature, compensated 21 °C to 77 °C [70 °F to 170 °F] Temperature effect, zero 0.002 % of rated output/°F Temperature effect, output 0.002 % of reading/°F For long cable runs or electrically noisy environments an amplified sensor or locally mounted amplifier is often preferred MODEL 2120 Display Units SC500 SC2001 GM 7541 SC1000 SC3004 NK 7558 SC2000 HH 7561-PSD 2003.1 lb.
