Temperature Transmitter – TTX – HCF / HRF

 

isolv

Temperature Transmitter – TTX – HCF / HRF. TTX is an in-head mounting 2-wire temperature transmitters for PT100 or thermocouple input. Designed for highest reliability and cost-efficiently manufactured.

tthx_ttx_topbar

• Multi-Range Design
TTX-HRF for Pt100 input with selectable measurement ranges

TTX-HCF for T/C J, L, T, K and N Inputs with Continuous Ranges Adjustment

• Accurate Measurements
- Temperature linear 4-20 mA output for Pt100 input.
- mV linear output for thermocouple

Easy Mounting and Access
- Flat design gives easy access to terminals and adjustments
- Large center hole lets the lead wires or an insert tube pass easily

• Safety
Genuine sensor break detection with selectable action,
upscale or downscale. Excellent EMC performance

• High Load

Capacity
Only 6.5 V voltage drop over the transmitter allows for high loads

tthx_ttx_applications

Temperature transmitters convert millivolt inputs from thermocouples or resistance from RTD’s into 4-20mA outputs.
