MODELS TMPT AND TMPTR - THERMOCOUPLE OR RTD CONNECTOR WITH
BUILT IN 4-20 mA TEMPERATURE TRANSMITTER
GENERAL DESCRIPTION
The model TMPT's internal circuitry conditions the non-linear millivolt
output of a thermocouple, across a specified temperature range, and retransmits
it as a standard 2-wire 4–20 mA analog output. The TMPTR also provides a
2-wire 4–20 mA output by conditioning the resistive change of a 100Ω, 0.00385
RTD sensor and transmitting it as a 4–20 mA output.
SPECIFICATIONS
TMPT SPECIFICATIONS
1. SUPPLY VOLTAGE: 9 to 24 VDC @ 30 mA
2. OUTPUT: 4 to 20 mA
3. TEMPERATURE RANGE: See Ordering Information
4. ACCURACY: ± 0.5% of full scale millivolt input @ 23º C plus the non-
linearity of the thermocouple type (note that the TMPT does not compensate
for thermocouple non-linearity)
5. TEMPERATURE COEFFICIENT: ± 0.002 mA/ºC
6. MAX LOOP LOAD: (Ω) = (V supply - 9 V)/0.02 A
7. TRANSMITTER OPERATING TEMPERATURE: -40º to 85ºC
8. AGENCY APPROVAL: CE
9. RESPONSE TIME: 120 msec (0 to 63% FS)
10. THERMOCOUPLE JUNCTION: Ungrounded
11. INPUT CONNECTION: Standard size female connector mates with both
standard and miniature male connectors.
12. CABLE CONNECTIONS: 10 foot 2-wire shielded cable
