Product Specification

CSB - Compact Sensor Board
Electronic Sensor Board for oxygen sensors by SENSORE Electronic

Compact Sensor Board
"CSB" (Compact Sensor Board) is an affordable option to operate only the amperometric sensor at conditions with low temperature variation.

In this case the sensor heater is operated with constant voltage. The output signal is not linearized and is only available as a voltage signal (0-5V).

CSB - Compact Sensor Board Main Features
• Compatible with O2-Sensor-types SO-zz-xxx
• Supply voltage 12Vdc
• Output signal 0-5V or 4-20mA according to O2-concentration
• Also available as calibrated package (sensor + electronic)
• Fixed heater voltage intended for ambient temperatures 0-40°C

CSB - Compact Sensor Board Characteristic Data

Sensor Compatibility

Compatible with sensors: SO-zz-xxx (see sensor data sheet)
TO-8 standard types can be mounted directly on the PCB
Other types can be connected via 6-pol. interface
Based on the selected sensor type, the sensor board will be delivered with a fixed configuration for sensor and heater voltage
Supply
Supply voltage: 12V ± 1V
Typical current consumption: 200mA
Measuring range
Depending on selected sensor type
Output characteristic:
Standard: Vout (O2) = 0-5V
Or alternative: Iout (O2) = 4-20mA (maximal resistive load: 100Ω)
Standard coefficients after calibration:

sensor type	max. O2[Vol.-%]	kU[V]	kI[mA]
SO-zz-010	1	497,50	1591,99
SO-zz-020	2	247,49	791,97
SO-zz-050	5	97,48	311,93
SO-zz-250	25	17,38	55,62
SO-zz-960	96	1,553	4,971

Calibration
Single point calibration via potentiometer
It is also possible to purchase an already calibrated system (electronic + sensor)
Accuracy
1% of measuring range @ T_ambient =25°C ±10°C (assuming a calibration at 25°C)
Response time (t90)
<20 sec. (depends on sensor type)
Warm up time
Approx. 2 min.
Permissible ambient temperatures
T_ambient=0 - 40°C for sensor directly mounted on the CSB

Higher sensor ambient temperatures are possible if a connection via 6-pol interface is used.
Such applications can be evaluated upon request.
