Transmittertypes, descriptions

Threaded transmitter R 1/2" and NPT 1/2”. (1 and 2)

The threaded transmitter with connection to R 1/2” thread is intended for clean media. At a media temperature higher than 90ºC, a cooling pipe is used to prevent too high temperature at the sensor. The threaded connection is normaly sufficient to keep the transmitter in place. At specific conditions or wall installation the transmitter can be supported and reinforced with an installation kit.

(Exceptions: Normally not available with tantalum diaphragm.)

Threaded transmitter with extended diaphragm, R1½”. (3)

This transmitter connection with a connection to a 1½” thread is intended for fibre-rich and viscous media. The extended front diaphragm is in connection with the media without any pocket inside the tank or pipe. An optional adapter is available for connection to a 2" thread and an optional welding sleeve for R1½”. There are no additional requirements on the installation. The transmitter may also be connected inside a threaded R1½” cylinder, such as a pipe sleeve or shut-off valve.

(Exceptions: Not available with tantalum diaphragm and pressure range 14 and 35 kPa. The highest pressure range for this connection type is 4 MPa).

Flange connected transmitter.

Flange 80 mm/3”, Flange 50 mm/2” and DRD flange. (4, 5 and D)
A flange connected transmitter is intended for level measurement in open tanks with liquid media, even with fibre rich and/or viscous media. The risk of blockage is eliminated by the large area of the exposed diaphragm. The transmitter is clamped between standard flange rings. The transmitter fits slip-on flanges of ANSI or DIN type. For transmitters with flange connection, the type of flange has to be stated at the time of order. (see Accessories). PTE200 with flange 50 mm/2" and six holes, for use with MWP10 is supplied upon request.

(Exceptions: Not available with tantalum diaphragm combined with pressure range 14 and 35 kPa. The highest pressure range for this connection type is 4 MPa. Note that the limits depends on flange type.)

Hygienic clamp connected transmitter. Clamp38, Clamp51 and Varivent. (9, A and V)

A clamp connected transmitter is used when special hygiene requirements are needed, such as those in the pharmaceutical industry. The design meets ISO 2852 and the transmitter is easy to install and remove. If clamp 38 connection is not available, the optional connector piece, clamping ring and gasket ring may be used. Connection details for clamp 51 and Varivent is available upon request but not available from stock.

(Exceptions: Normaly not available with tantalum or stainless steel diaphragm. The highest pressure range for clamp 38/51 and Varivent is 2 MPa. Note that the limits depends on clamping ring type.)

Hygienic screw connected transmitter. DIN11851/40 mm, SMS Rd60-6, DIN11851/50 mm. (7, 8, C, E)

A screw connected transmitter giving a hygienic connection, for example, used in the Dairy industry. The exposed diaphragm has direct contact with the media which make it possible for the transmitter to measure even viscouse liquid media, without becoming silted up. The transmitter is installed in accordance with the Rd 60-6 connection of SMS 1146, DIN 405 and DIN 11851. The transmitter is screwed to the connector.

(Exceptions: Normaly not available with tantalum or stainless steel diaphragm. The highest pressure range for DIN11851/40 is 2 MPa. The highest pressure range for SMS Rd60-6 is 8 MPa.)

Transmitter removable during operation. (6)

This transmitter type is intended for liquid media, even with viscous or fibre-rich media. The extended diaphragm is in connection with the media without any pocket inside the tank or pipe. The transmitter can be exchanged during operation and comprises three parts; the transmitter, a ball valve and a welded casing/compression flange. This compression flange is designed to fit an ANSI or DIN 80 mm/3” flange and may be installed to measure levels according to the hydrostatic principle.

(Exceptions: Normaly not available with tantalum diaphragm. The highest pressure range for this transmitter type is 2 MPa.)

Differential pressure transmitter. (G, H and T)

Differential pressure transmitters is used to meausre the difference between two pressures. The transmitter types G and H can withstand high static pressures, both one- and doublesided, (up to 15 MPa). The transmitter type G has threaded connection and type H has one side threaded and the other side with flange 80 mm. They are used for level measurements in pressure vessels and flow measurements of gases, liguids and vapour. Other application areas are differential pressure measurements across filters or heat exchangers, and pressure measurements with narrow measurement ranges where there is a danger of high one-sided pressure overload. The differential pressure transmitter type T can be delivered with two process connections 3-9, A, C, D, E och V. One side is directly connected to the transmitter and the other side with a capillary tube (normal lenght of the capilary tube is 2000 mm, other length upon request).

(Execeptions: Type G: Threaded connection is not available with tantalum or stainless steel diaphragm. Flange connection is not available with Tantalum diaphragm.The highest pressure range is 0,8 MPa. Type T: Highest static pressure is the same as the overload for the pressure range. Same exceptions as for the choosen process connection.)

Transmitter with capillary tube. (N)

This transmitter type is designed with the connection (with the measuring diaphragm) separated from the transmitter housing. The media pressure is transferred via a capillary tube (normal lenght of the capi lary tube is 1000 mm, other length upon request) to the sensor located in the transmitter housing. This type can be delivered with process connections 3-9, A, C, D, E and V. The transmitter type is designed for applications with high vibration levels or high ambient temperatures. Withstands extremly high media temperartures.

(Exceptions: Same exceptions as for the choosen process connection.)
