1. General items
1.1 Introduction
The SMT3000 is a product to measure the temperature of liquids, gases or vapors and it is specially
designed for use throughout industrial processes. The HART® communication is possible for this
product and parameters can be set using a PC or HART® communicator. Substances of which the
temperature can be measured are gases or liquids suitable for the sensing unit materials of the
product. This is described in detail in the data sheet, and the contact materials in each different
process should first be checked whether they are compatible with parts of the sensing unit. Reliable
technical data is contained in the data sheet of the transmitter, if you do not have the data sheet,
please request it from us or download it from our website. (www.wisecontrol.com)
1.2 Application
Temperature sensors are used for temperature measurements in various processes. Measured values
are used for indication, recording and control in control panels or process systems. Depending on the
process situation, an appropriate thermowell may be selected and used, or a temperature sensor may
be inserted directly into a pipe without a thermowell.
1.3 Warranty
If one causes damage to the product due to failures to comply with the user manual, or if one
arbitrarily remodels it, changes or repairs the product, the manufacturer will not be responsible for it,
and the product warranty period will expire.

4. Design
4.1 Structure
4.1.1 Basic type
Products generally come in two types: explosion proof and general. Explosion proof products are
resistance against pressure and explosion. The enclosure is designed to withstand the pressure of
explosive gases or vapors exploding inside, and to prevent combustion due to explosive gases or
vapors outside the enclosure through joints and lead-ins. The basic type of the products are comprised
of a detector unit and process connection unit welded together. An appropriate process connection
unit may be selected and used depending on the installation environment. The temperature sensor
may be installed by inserting directly, or together with a thermowell appropriate to the use environment.
4.1.2 Spring loaded type
In the spring-loaded type, a spring is installed inside the head, and the load from the spring allows the
sensor to maintain maximum contact. Detection response time is faster compared to the basic type.
Spring-loaded type sensors are not sealed to allow for movement of the detector unit, and are typically
installed together with a thermowell appropriate to the use environment. When installing the
temperature sensor directly, contact between the process fluid and temperature sensor should be
avoided, or a sealed type sensor should be used instead.
4.1.3 Remote type
In the remote type, an extension table extends out beneath the head and is connected to a sheathed
cable. The actual measuring element is inside the sheathed cable, and the distance between the head
and measuring element can be selected according to the installation location. The extension cable is
typically insulated stainless steel. Depending on the installation environment, a wall-mount bracket or
2” bracket may be used.

increase

2) Process Extension length: Distance between thermowell or process line to head
/ Lead wire connection length): Length of extension cable or extension & compensating wire
* The process connection unit length of units installed in explosion proof areas must be sufficient
to keep the temperature increase at less than 20°C.
※Caution: When installing a temperature sensor unit to satisfy the surface temperature condition (T6:
85℃), please proceed according to the figure below.

4.6 Transmitter failure (NAMUR NE43)
NAMUR NE43 means failure indication when signals of 3.6 mA or less or 21 mA or more which are not
within the normal instrument output range of 4-20 mAare detected. The 3.8~20.5mAsignal section is
used as the normal measurement signal, and the signal ≥21mA or ≤3.6mA can be checked with failure
alarm.
Transmitter failures can be caused by sensor or converter failures. When such a failure occurs, the
smart device will output a signal of 3.6mA or 21mA depending on the fail safe mode set by the user.
Recently, there are many transmitters and equipment that can set fail safe mode according to the
NAMUR NE43 standard and choose one between low alarm and high alarm modes.
*Note.
Failure can be selected between Low alarm and High alarm.
The standard setting of failure alarm is High alarm.
