Typical Applications
Construction
Self-contained temperature transmitter employing a platinum sensing element, 1000 Ω (±0.1%) at
32°F (0°C). Duct averaging models TSP-84704, TSP-84804, TSP-85703 and TSP-85803 employ
Balco sensing element, 1000 Ω ±1.0% at 70°F (21°C). All models are housed in a sturdy plastic
enclosure.
Output signal
Variable 4 to 20 mAdc for linear signal. High temperature = 20 mAdc,
mid-range temperature = 12 mAdc, and low temperature = 4 mAdc.
Span 16 mAdc (non-adjustable).
Current limit 30 mAdc.
Linearity 0.01% of span.
Hysteresis (deadband) 0%.
Short circuit duration Continuous.
Response time 400 microsec at full load.
Load resistance 25 through 900 Ω, dependent on power supply voltage. Refer to Figure 1.
Sensing element Duct averaging elements are ±1.8% of span.
Resistance change
Platinum: 2.14 Ω per F degree (3.85 Ω per C degree).
