Combination Probe KS1D - Zirconium Dioxide Probe

Simultaneous measurement of the concentration of O₂
and oxidising gas constituents (CO/H₂)

Heated, electro-chemical measuring cell, made of zirconium dioxide ceramic (ZrO₂)
Use of proven measuring principles
Simultaneous measuring of oxygen O₂ and detection of oxidisable (combustible) parts of flue gas
Display as COequivalent (CO_e)
Cost-efficient measuring for monitoring and optimisation of oil- and gas combustions

Range of measuring O₂:	0...18%Vol. O₂ - with limitations 0...21 Vol.% O₂ CO_e: 0...1.000 ppm CO_e, 0...10.000 ppm CO_e on request
Preciseness of measuring:	O₂: +-5% of measuring value – not better than +- 0,3 Vol.% CO_e: +-25% of measuring value – not better than +- 10 ppm after prior alignment of application conditions with a CO reference measuring in a range of measuring 0...100 ppm: <= 10 ppm
Response time t60: (60% of final value)	O₂ <= 10 seconds CO_e <= 2 seconds
Failure impact:	Change of temperature of measuring gas in dependency of preciseness of temperature control of ZrO₂ measuring cell
Cross-sensitivity:	Against SO₂, NH₃, NO, Propan, other arenes

Operating temperature (KS1-D sensor)	Probe housing <= 400°C (measured at hexagonal) Cable bushing <= 200°C Connecting cable <= 150°C
Durability	>= 3 years at oil and domestic gas
Probe output voltage	800...-30mV (O₂-electrode) <-> 0...21 Vol. % O₂ -30...800mV (CO/H₂-electrode) <-> 0...10.000ppm CO_e
Probe internal resistance RI in air at 20 °C and 20 W Heat output (new probe)	15...30 Ohm O₂ - electrode 1 15...30 Ohm CO/H₂ - electrode 2
Heat output at ambient temperature	18...25 W - depending on type
Isolation resistance between heating and probe connector	> 30 MΩ
Power supply	At connector (D/C- A/C voltage) at PH 18 VA → 11,4 V at PH 20 VA → 12,34 V at PH 25 VA → 14,8 V
Heat output for TGas = 350 °C	Appr. 18 W
Heat current at PH 20 VA	Appr. 1,6 A Appr. 5A shortly at heating-up PTC-characteristique
Dimensions of probe KS1D sensor KS1D with housing	Length 115 mm; thread M18 x 1,5 mm Length 185 mm; R 1 1/4“, D=31,75 mm

Purpose

The combination-probe KS1D is qualified for measuring at places or spots, which are marked by infiltrated air, as well as in multi-burner applications, for which a sole O₂ measuring cannot give any statements for atmosphere or combustion process respectively a fast response is needed. It is used in applications controlling oven atmosphere at measureing gas temperatures up to 1400 °C.

It is applied to gas combustions of all types, wood- and carbon-dust combustions as well as garbage combustion plants, glow- and melting ovens and crematoriums.
