General:
The Model WTZ-288 Electric Contact Thermometer is designed to take measurement and control of the
temperature ranging from -20ºC to 120ºC in non-corrosive site within a distance of 16 m.
With the application of working principle of pressure-type thermometer, the WTZ-288 is featured by being
simple structure, easy to use and at moderate price.
Contact thermometer is suitable to within 16 m, Measuring range is (+20º C~+120º C) with no cauterization
occasion in measuring and controlling. Model WTZ-288 series contact thermometer adopts the elements of
pressure thermometer, it has a handy structure, use simple and convenient, the low price and so on.
Main Technical Parameters:
1, The temperature dimension and measuring rage:
Dimension range: -20~+60 0~100 20~120
Measuring range: 20~60 40~100 60~120
2, Indicative accuracy: 1.5 grade
3, Trail length(m): 3, 5, 10, 16. (According to the clients request, If it isn't show clearly the length, according to
5m)
Recommended added circuit
The power rating of each electric contact in the WTZ-288 is only 10VA without reactance, so users have to
resolve the problem of the contact power magnification. For your convenience, we would rather recommend you
a power magnification circuit with anti-oscillation and arc extinction (refer to figure 3).
Circuit Feature: Once the lower limit contact closes, the lower limit circuit gets self-locked. Only dose the upper
limit contact close, the ower limit circuit unlocks. Therefore, the electric contacts are well protected.
