U-GAGE®Q45U Specifications

Sensing Range	Near limit: 100 mm min.		Long Range: Near limit: 250 mm min.
	Far limit: 1.4 m max.		Long Range: Far limit: 3.0 m max.
	NOTE: The far limit may be extended on long range units, as far as 3.9 m for good acoustical targets
	(hard surfaces with area greater than 100 cm2)
Supply Voltage and Current	Discrete: 12 to 24V dc (10% max. ripple); 100 mA (exclusive of load)
	Analog: 15 to 24V dc (10% max. ripple); 100 mA (exclusive of load)
Ultrasonic Frequency	Long Range: 128 kHz		Short Range: 230 kHz
Supply Protection Circuitry	Protected against reverse polarity and transient voltages.
Output Protection Circuitry	Protected against false pulse on power-up and continuous overload or short-circuit of outputs.
Output Configuration	Discrete: Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor.
	Analog: One voltage sourcing and one current sourcing; one or the other output is enabled by internal
	programming switch #2.
Output Ratings	Discrete: 150 mA max. (each)
	OFF-state leakage current: less than 25 µA at 24V dc
	ON-state saturation voltage: less than 1.5V at 10 mA; less than 2.0V at 150 mA
	Analog: Voltage sourcing: 0 to 10V dc, 10 mA max.
	Current sourcing: 4 to 20 mA, 1 to 500 Ω impedance
Performance Specifications	Analog resolution or	Short Range		Long Range
	discrete repeatability: ± 0.1% of sensing distance			± 0.1% of sensing distance
	Analog Linearity:	(± 0.25 mm min.)		(± 0.5 mm min.)
		1% of full scale		1% of full scale
	Temperature effect: 0.05% of sensing distance/ ° C with temp. comp.			0.05% of sensing distance/° C
	Min. window size:	0.2% of sensing distance/ ° C without temp. comp.
		10 mm		25 mm
	Hysteresis (discrete output): 5 mm			10 mm
Response Curves	Short Range: See charts RC-2 and RC-4 on page 516.
	Long Range: See charts RC-3 and RC-5 on page 516.
Adjustments	The following may be selected by a 4-position DIP switch located on top of the sensor, beneath a
	transparent o-ring sealed acrylic cover:
	Discrete: Switch 1: Output normally open/normally closed (pump in/pump out)
	Switch 2: High/Low level control mode or on/off presence sensing mode
	Switch 3 & 4: Response speed selection (digital filter)
	Analog: Switch 1: Output slope positive or output slope negative
	Switch 2: Current output mode or voltage output mode
	Switch 3: Loss of echo min/max mode or loss of echo Hold Mode
	Switch 4: Loss of echo min/max default output value
Indicators	Discrete: Three status LEDs:
	Green ON steady: power to sensor is ON
	Green flashing: output is overloaded
	Yellow ON steady: outputs are conducting (Yellow LED also indicates programming
			status during setup mode)
	Red flashing: indicates relative strength of received echo
	Analog: Three status LEDs:
	Green ON steady: power to sensor is ON
	Green flashing: current output fault detected (the 4-20 mA current path to ground has
		been opened)
	Yellow ON steady: target is sensed within the window limits (Yellow LED also indicates
			programming status during setup mode)
	Red flashing: indicates relative strength of received echo
	5-segment moving dot LED indicates the position of the target within the sensing window.
