E+H iTHERM ModuLine TM101 Temperature Sensor

Fits industrial (non-hazardous) direct-process temperature points that need a modular metric RTD or thermocouple with optional iTEMP head transmitter — family span −50 to +650 °C, Pmax 50 bar, threads/compression fittings per ModuLine.

Key advantages

Measuring range — Overall family −50 to +650 °C (−58 to +1202 °F); Pt100 TF basic −50 to +200 °C; TC Type K options per TI01446.
Sensor options — Modular RTD (Pt100 TF/WW) or thermocouple; direct process contact metric thermometer.
Output — Direct-wired sensor or iTEMP head transmitter: 4–20 mA, HART, IO-Link.
Process pressure — Pmax = 50 bar (725 psi).
Ingress protection — Up to IP66 / partly IP68 depending on terminal head/connector design.

Typical applications

Industrial process temperature where a basic ModuLine metric thermometer is specified (non-hazardous base offering).
RTD Pt100 TF loops needing Class A / Class AA inserts with optional head transmitter.
Direct process contact with thread or compression-fitting process connections.
Replacement of modular RTD/TC inserts where TM101 family span and 50 bar Pmax cover the duty.

Selection guide

Sensor type — Lock Pt100 TF/WW vs Type K (and other TC) before RFQ; accuracy Pt100 Class A / Class AA per IEC 60751 (sensor type dependent); optional iTEMP transmitters improve system accuracy.
Transmitter — Direct-wired vs iTEMP 4–20 mA / HART / IO-Link changes wiring and system accuracy.
Process connection — Wide range of threads and compression fittings (metric ModuLine).
Ambient / head — Per terminal head / transmitter selection (see TI01446).
Approvals — Industrial (non-hazardous) base offering per TM101 positioning — use TM111 when Ex marks are required.

Common mistakes

Ordering TM101 when the loop needs ATEX/IECEx/CSA — TM101 is positioned as industrial non-hazardous; TM111 carries Ex options.
Leaving insert type blank — Pt100 TF basic tops at +200 °C while the family goes to +650 °C with other sensors.
Assuming every head is IP68 — ingress is up to IP66 / partly IP68 depending on terminal head/connector.
Skipping transmitter choice — direct-wired sensor vs iTEMP 4–20 mA/HART/IO-Link changes termination and accuracy budget.

When to RFQ / what to tell us

Sensor type (Pt100 TF/WW vs TC), insert length/diameter, and Class A vs Class AA need.
Process connection (thread/compression), Pmax/media T, and whether iTEMP 4–20 mA/HART/IO-Link is required.
Quantity, ship-to, and confirmation that non-hazardous (no Ex) is acceptable — otherwise quote TM111.

FAQ

Q: TM101 vs TM111? A: TM101 is the basic industrial (non-hazardous) ModuLine metric thermometer to 50 bar. TM111 adds QuickSens, higher pressure/temperature options, and Ex approvals — pick by Ex need and span.

Q: What outputs are available? A: Direct-wired sensor or iTEMP head transmitter with 4–20 mA, HART, or IO-Link.

Q: What should I send for a quote? A: Sensor type, connection, media T/P, transmitter need, quantity, ship-to. Compatible with systems using E+H iTHERM ModuLine TM101 — we do not claim authorized-dealer status.
