ABB provides head-mounted temperature transmitters, for standard type B sensor heads; field-mounted temperature transmitters; and rail-mounted temperature transmitters, which can be mounted in confined spaces such as connector boxes or cabinets.

Ultra Electronics is a supplier of head-mount, programmable temperature transmitters; head-mount temperature transmitters; head mount, programmable RTD temperature transmitters; DIN, rail-mount temperature transmitters; and DIN, rail-mount programmable temperature transmitters.

SMAR designs and manufactures temperature transmitters intended for measurement of temperature using RTDs or thermocouples. The company also produces panel-mount, smart temperature transmitters; and head-mount, smart temperature transmitters that feature two-wire, 4-20mA output signals.

Thermocouple Technology Inc. engineers and designs an isolated, 2-wire, in-head transmitter for temperature and other measurement applications. The company also design compatible intelligent transmitters.

Pyromation manufactures mounted or surface-mounted, programmable temperature transmitters that send a scaleable 4 to 20 mA signal from a temperature sensor to a control device, without investing thermocouple or RTD wire. Some of the company's transmitters are approved for use in hazardous locations.

Pyragon manufactures a line of 2-wire temperature transmitters that includes: a tiny transmitter that mounts inside a sensor head; a compact DIN rail mount; and a fully-featured  temperature transmitter with built-in digital display.
